Easy Cherry Syrup Recipe With Fresh or Frozen Cherries

Cherry syrup is one of the easiest preserves you can make: cherries, sugar and water, a gentle simmer, and a strainer.

What decides if yours tastes like fresh fruit or like cough medicine is a handful of small choices along the way, such as how hard it cooks, how much fruit you use and when the lemon goes in.

Below you’ll find a dependable recipe that works with fresh or frozen cherries, plus what to change for a pancake-thick sauce, a sour cherry version or a jar that keeps on the pantry shelf. You’ll also know how long it really lasts and how much to pour.

Cherry syrup at a glance

• Basic ratio: 2 cups cherries to 1 cup each of sugar and water, plus a little lemon juice
• Time: about 30 minutes of cooking and resting, then cooling
• Yield: about 1¼ to 1½ cups (300 to 350 ml)
• Keeps: plan on about 2 weeks in the fridge, or about 3 months in the freezer
• Cherries: fresh or frozen; sweet or sour; pitted or not, as long as you strain it

Pick a Method Before You Start

Most recipes are a version of one of four approaches. They differ in how long the fruit spends over heat, and that is what moves the flavor from bright and fresh toward jammy and cooked.

Method	What you do	What you get
Simmer (the recipe below)	Cook everything in one pot for 10 to 15 minutes, then strain	Good color and full flavor with little fuss; the all-purpose choice
Steep	Dissolve the sugar in hot water, take it off the heat, add cut fruit and leave it for about an hour	The freshest, most floral taste, but paler and a little thinner
Juice first	Simmer fruit in water, strain, then stir the sugar into the hot juice	Deep color and concentrated flavor; easy to control sweetness
No water	Mash fruit with sugar alone and cook until it releases its juice	The most intense syrup, with a smaller yield per pound of fruit

Fruit-to-liquid ratio matters as much as method. Recipes range from 1 cup of cherries per cup of water to 4 cups of fruit with only ½ cup of sugar.

More fruit means more color and flavor in every spoonful. More sugar, compared with water, means a thicker syrup that keeps longer. The recipe below sits between the two.

Choosing Your Cherries

Any cherry will make syrup, but the variety sets the color and how much sugar tastes right.

• Dark sweet cherries (Bing, Lapins, Chelan, Sweetheart) give the deep garnet syrup most people have in mind, with a round, mellow sweetness. Add the lemon juice; it keeps the flavor from going flat.
• Blush cherries (Rainier, Queen Anne) are very sweet but make a pale pink-amber syrup. Lovely in a clear drink, disappointing if you wanted red.
• Sour cherries (Montmorency, Morello) give the most distinctly cherry flavor and a vivid red. Their acidity carries more sugar, so they suit richer ratios like the one in the variations section.

Season depends on where you live.

In North America, fresh sweet cherries are usually around from late spring to late summer, while in Australia, New Zealand and South America they arrive around the end of the year. Fresh sour cherries are harder to find almost everywhere.

In the US most of the tart crop comes from Michigan and nearly all of it is sold frozen, canned, dried or juiced, so check the freezer aisle, farmers markets in July, or Middle Eastern and Eastern European grocers, which often stock frozen or jarred sour cherries.

Frozen cherries are a strong choice, not a fallback. They come pitted, they were frozen ripe, and freezing breaks down the fruit’s cell walls, so they give up juice and color quickly.

Read the bag: you want unsweetened cherries, not cherries packed in syrup, and it’s still worth feeling for the odd stray pit. F

resh fruit has the edge on aroma. Slightly bruised or soft cherries are perfect here, since they get strained out anyway.

Basic Cherry Syrup

A pourable syrup for drinks that also works on pancakes. Makes about 1¼ to 1½ cups (300 to 350 ml).

You’ll need:

• 2 cups (300 g, about 11 oz) cherries, stemmed, halved and pitted if you like (fresh or frozen)
• 1 cup (200 g) granulated sugar
• 1 cup (240 ml) water
• 1 tablespoon (15 ml) lemon juice
• A pinch of salt (optional)
• A stainless steel or enameled saucepan, a fine-mesh strainer and a clean glass jar

White sugar is the right default: it keeps the color bright and lets the cherry lead. You can use brown sugar, honey or maple instead; expect a darker syrup with their flavor layered over the fruit.

1. Put the cherries, sugar and water in the saucepan. Frozen cherries can go in straight from the freezer; don’t thaw and drain them, because that liquid is juice you want. Avoid bare aluminum, which reacts with fruit acid and can dull the color.

2. Set the pan over medium heat and stir until no sugar crystals remain and the liquid turns clear.

3. Lower the heat to a gentle simmer, with small, lazy bubbles rather than a rolling boil. Give it 10 to 15 minutes, nudging the fruit against the side of the pan now and then to help it release. Frozen fruit needs a few extra minutes to come up to heat.

4. Stop when the cherries look collapsed and pale and the liquid is glossy and deep red. Longer cooking won’t add cherry flavor; it drives off the fresh aroma and starts pushing the color toward brown.

5. Take the pan off the heat and stir in the lemon juice and salt. Acid keeps the red brighter, and adding it off the heat keeps its taste fresh. Let it sit for 10 minutes.
6. Strain into a heatproof bowl or measuring cup. Let it drip for a clear syrup, or press the fruit with a spoon for more yield and a slightly cloudy one.

7. Cool it uncovered until it stops steaming, then pour it into the jar, cap it and refrigerate. A lid on hot syrup traps condensation, and water dripping back onto the surface shortens its life.

If you pitted the fruit, keep the strained cherries. They’re soft, sweet and good over yogurt, ice cream or oatmeal for a few days in the fridge.

To try one of the other methods from the table, use the same ingredients unless noted and add the lemon juice off the heat as before:

• Steep: heat the sugar and water until clear, take the pan off the heat, add the halved cherries, cover and leave for 1 hour before straining.
• Juice first: simmer the cherries in 2 cups (480 ml) water for 15 minutes, strain, then stir the 1 cup of sugar into the hot juice until it dissolves.
• No water: mash 1 lb (450 g) stemmed cherries with ¾ cup (150 g) sugar as they warm, gently if unpitted, simmer about 15 minutes and strain. Expect about 1 cup (240 ml).

Do You Have to Pit the Cherries?

No, not for a strained syrup. You’ll see warnings about cyanide in cherry pits, and the concern is real but specific.

The compound involved, amygdalin, sits in the kernel inside the pit’s hard shell. Poison centers explain that the danger comes when pits are chewed or crushed, which releases it, while swallowing one or two whole pits by accident won’t cause harm.

The National Center for Home Food Preservation’s tested recipe for canning whole cherries leaves pitting up to you, which tells you intact pits are an accepted part of cooking cherries.

So the rule is simple: never do anything that could break the pits. A gentle press with a spoon on soft, cooked fruit is fine. A blender, food processor or heavy pounding is not, so pit first if your method involves any of those.

Pit too if you want to eat the strained fruit, leave pieces in the syrup or serve it to small children, since a stray pit is a choking risk.

You’ll read that pits either add a lovely almond note or a bitter one. Any effect through an intact shell is subtle, so it’s not a reason to leave them in. If you want that almond flavor, ¼ teaspoon of almond extract does it reliably.

No pitter? Stand a cherry stem end up on the mouth of an empty bottle and push a chopstick or sturdy straw through it; the pit drops into the bottle. For a small batch, halving each cherry and flicking out the pit with a paring knife is just as quick.

Getting the Thickness Right

Hot syrup is much thinner than it will be once chilled, which is why so many first batches either seem watery and get overcooked, or set into something sticky by morning.

Judge it cold. Put a spoonful on a saucer and chill it in the freezer for a minute or two, then run a finger through it. If the line stays open, the jar will pour like that tomorrow.

For a thicker result, choose one of these approaches:

• Change the ratio.

Using 1½ cups (300 g) sugar to 1 cup (240 ml) water gives a syrup that coats a spoon and still dissolves in drinks.

• Reduce it.

Simmer the strained syrup for another 5 to 10 minutes. You’ll trade away a little freshness, which matters less on pancakes than in soda water.

• Make a sauce.

Stir 2 tablespoons cold water into 1 tablespoon cornstarch until smooth, stir it into the simmering syrup and cook for 1 to 2 minutes until glossy. Pit the cherries first and leave some fruit in for a pancake or ice cream topping.

Never add dry cornstarch straight to the pan, and keep this version for the fridge or freezer, not the canner.

Variations Worth Making

• Sour cherry syrup: 1 lb (450 g) pitted sour cherries, 2¼ cups (450 g) sugar and 2 cups (480 ml) water, simmered about 20 minutes. Skip the lemon; the fruit brings its own acid. This richer syrup is the base for sharbat, the Persian chilled drink, when stirred into iced water.
• From bottled tart cherry juice: simmer equal volumes of unsweetened tart cherry juice and sugar for 15 to 20 minutes. No pitting, any time of year. If your juice is sweetened, cut the sugar.
• Almond: ¼ teaspoon almond extract, off the heat. Start small; too much tastes artificial. Leave it out for anyone with a tree-nut allergy.
• Vanilla: 1 teaspoon vanilla extract stirred in after cooking, or half a split vanilla bean simmered with the fruit.
• Spiced: simmer a cinnamon stick, two or three cloves or a single star anise with the fruit, then let it steep for 10 minutes before straining.
• Citrus or herb: a strip of orange or lime peel, or a sprig of rosemary or thyme, during the simmer. For a cherry limeade base, swap the lemon for 2 tablespoons lime juice.
• Less sugar: you can cut the sugar or use a sugar substitute, but the syrup will be thinner and spoil faster.

How Long Cherry Syrup Keeps

You’ll find everything from 4 days to 6 months quoted, and the spread has real causes: how much sugar the syrup holds, whether fruit pulp is left in it and how clean the jar was.

Here’s what to plan on.

• Basic strained syrup, refrigerated: about 2 weeks. Use a clean jar, pour rather than dip, and keep it at the back of the fridge, not in the door.
• Richer, higher-sugar syrups such as the sour cherry version usually keep longer, often a month or so, but check them as you go.
• Syrup or sauce with fruit pieces left in, and low-sugar versions: a few days to a week.
• Frozen: measure 1 tablespoon into each well of an ice cube tray, freeze, then bag the cubes so each one is a known amount. Use within about 3 months for the best flavor. If you freeze it in a jar, leave ½ inch (1.25 cm) of space for expansion.

Throw it out if you see bubbles or fizz in a jar nobody has moved, a film or fuzzy spots on top, or smell anything yeasty, winey or sour. A little sediment that settles at the bottom and stirs back in is normal.

Don’t try to skim mold off. For jams and jellies, USDA now advises discarding the whole jar rather than scooping out mold, and syrup deserves the same caution.

Canning Cherry Syrup for the Pantry

A refrigerator recipe isn’t a canning recipe, and you’ll see processing times online that range widely, some with lemon juice and some without.

For a shelf-stable jar, use the tested Berry Syrup recipe from the National Center for Home Food Preservation, which names cherries among its fruits, and follow it exactly:

1. Wash and stem 6½ cups (about 1.5 L) fresh or frozen cherries, crush them in a saucepan (gently, if they still have pits), bring to a boil and simmer until soft, 5 to 10 minutes.
2. Strain the hot fruit through a colander and let it drain until cool enough to handle, then strain the collected juice through a double layer of cheesecloth or a jelly bag. Expect 4½ to 5 cups (1.1 to 1.2 L) of juice.
3. Combine the juice with 6¾ cups (1.35 kg) sugar in a large saucepan, bring to a boil and simmer 1 minute. Skim off the foam.
4. Fill clean half-pint or pint jars, leaving ½ inch (1.25 cm) of headspace, and adjust the lids.
5. Process hot-packed jars in a boiling-water canner for 10 minutes at up to 1,000 ft (305 m), 15 minutes at 1,001 to 6,000 ft (1,830 m) and 20 minutes above 6,000 ft. It makes about 9 half-pints.

The processing times were tested for this recipe, so don’t swap in your own ratio or add cornstarch. The center lists Clear Jel as the starch for canned pie fillings because ordinary starches break down in the jar.

Fixing a Batch That Went Wrong

• Thin even when cold: simmer it a few minutes longer, or add a cornstarch slurry if it’s headed for pancakes.
• Sweet but flat: add a pinch of salt and lemon juice by the teaspoon, tasting as you go. Missing acid is the usual problem, not missing fruit.
• Brown or dull instead of red: it cooked too long or too hard. Next time, keep the bubbles gentle and add the lemon juice.
• Cloudy: you pressed the fruit hard. Nobody will notice in soda. When clarity matters, run this batch through a coffee filter and let the next one drip on its own.
• Gritty crystals in the fridge: the sugar didn’t fully dissolve, or the syrup is very rich. Warm it gently with a spoonful of water.
• Tastes like pie filling: Try the steep method for a fresher flavor.
• Bitter, almond-like edge: pits may have cracked. Pit the fruit next time if you mash firmly.

How to Use It, and How Much

Start with these amounts and adjust to your taste.

• Cherry soda: 2 tablespoons (1 oz / 30 ml) syrup in 6 oz (180 ml) cold sparkling water, poured over ice and finished with lime. Go up to 3 or 4 tablespoons for soda-fountain sweetness, or add a splash of cream for an Italian soda.
• Iced tea and lemonade: 1 to 2 tablespoons a glass.
• Coffee: 1 tablespoon in an iced latte or a mocha. More than that and it turns into dessert.
• Cocktails: swap it one for one with simple syrup, for example ¾ oz (22 ml) in a whiskey sour, or use it wherever a recipe calls for grenadine, such as a Shirley Temple.
• Breakfast and dessert: warm the thicker version for pancakes, waffles and ice cream, or swirl it into yogurt and oatmeal.
• Cake: brush the thin syrup over warm cake layers before frosting for moisture and a quiet cherry flavor.
• Savory: reduce it with a splash of balsamic vinegar to glaze pork or duck, or whisk a spoonful into a vinaigrette.

Cherry Syrup FAQ

Is cherry syrup the same as grenadine?

They are different syrups. Grenadine is traditionally a pomegranate syrup, though many bottled versions are mostly sugar, flavoring and red dye. Homemade cherry syrup works in its place in drinks, with a deeper, darker fruit flavor.

Can I make it with maraschino cherries?

You can, but you’ll get the bright candy flavor of the jar rather than real cherry. Maraschino cherries are already sweetened and colored, so simmer the cherries with their jar liquid and cut the sugar well back.

Can I double the recipe?

Yes. Keep the same ratio and use a wider pan so the fruit still sits in a shallow layer. It will take a few more minutes to come to a simmer, but the cooking time once it bubbles stays about the same.

Your First Batch

Make one small batch this week with whatever cherries you can get, frozen included, and taste it in a glass of sparkling water before you decide what to change.

Once you know how it behaves, try the steep method or a sour cherry batch side by side, and keep the version you reach for most.

How to Can Tomatoes: A Step-by-Step Guide for Beginners

Canning tomatoes at home comes down to three things you can’t skip: added acid in every jar, a tested processing time for the style you’re making, and enough boiling water over the jars for the whole time. Get those right and the rest is ordinary kitchen work, mostly peeling and stirring.

Below, you’ll can crushed tomatoes from start to finish, since that style is the most forgiving and the most useful in cooking, and see what changes if you’d rather put up whole or halved fruit.

At a glance

• Method: boiling-water canner (a pressure canner also works).
• Acid per jar: 2 tablespoons (30 ml) bottled lemon juice or ½ teaspoon citric acid per quart; half that per pint. Never optional.
• Crushed tomatoes: ½-inch (1.3 cm) headspace; process pints 35 minutes, quarts 45 minutes at up to 1,000 feet (305 m).
• Tomatoes needed: about 2¾ to 3 pounds (1.25 to 1.4 kg) per quart jar.
• Time: plan on 3 to 4 hours for your first canner load of 7 quarts.

Why Tomatoes Need Added Acid

Tomatoes sit right on the line between high-acid and low-acid foods. The dividing point is a pH of 4.6.

Below it, the bacterium that causes botulism can’t grow in a sealed jar, so a boiling-water bath is enough. Above it, only the higher temperature of a pressure canner is safe.

Many tomatoes test just under that line, but some varieties, and fruit that is overripe, shaded or picked from a dying vine, can drift above it, and you can’t taste the difference.

Adding a measured amount of acid to each jar removes the guesswork. It applies to every tomato, including heirlooms, which aren’t any less acidic than modern varieties despite what you may have heard.

Per quart jar, add one of these: 2 tablespoons bottled lemon juice, ½ teaspoon (2.5 ml) citric acid, or 4 tablespoons (60 ml) vinegar of 5% acidity.

Per pint (473 ml), use half: 1 tablespoon (15 ml) lemon juice, ¼ teaspoon (1.25 ml) citric acid or 2 tablespoons vinegar.

Use bottled lemon juice, not fresh. Commercial juice is standardized to a consistent acidity, while the acidity of a fresh lemon varies with its ripeness.

Citric acid, sold in the canning aisle, has no flavor beyond tartness, which makes it my pick for tomatoes. Vinegar works but can leave a pickled edge.

If the jars taste sharp when you open them, a pinch of sugar at serving time fixes it.

Choose Your Style: Crushed, Whole or Sauce

Each style has its own tested headspace (the gap you leave between the food and the rim of the jar) and processing time, so decide before you start. Times below are for a boiling-water canner at up to 1,000 feet (305 m).

Style	Headspace	Pints	Quarts
Crushed (no added liquid), hot pack	½ inch	35 min	45 min
Whole or halved, packed in water, raw or hot	½ inch	40 min	45 min
Whole or halved, packed in tomato juice or raw with no liquid	½ inch	85 min	85 min
Tomato sauce, thin or thick, hot pack	¼ inch (6 mm)	35 min	40 min

Above 1,000 feet, add time. Water boils at a lower temperature as elevation rises, so the jars need longer.

For all four styles, add 5 minutes at 1,001 to 3,000 feet (305 to 914 m), 10 minutes at 3,001 to 6,000 feet (914 to 1,829 m), and 15 minutes above 6,000 feet.

If you don’t know your elevation, a mapping app will show it, or your local Extension office can tell you.

Crushed tomatoes are where I’d start. You cut the tomatoes into quarters and cook them briefly, so there’s no fussing with whole fruit, and the jars go straight into soups, chili and pasta sauce.

Whole or halved tomatoes in water look lovely and hold their shape for dishes where you want visible pieces, but they’re watery in the jar.

The two no-added-liquid whole packs give the best flavor of the whole styles, at the cost of an 85-minute boil.

Sauce takes the most tomatoes and the longest stove time, because you cook it down by a third to a half before it goes in jars.

Choosing and Buying Tomatoes

Choose firm, ripe, unblemished tomatoes. Skip any with soft spots, cracks, mold, blossom-end rot or insect damage, and never can fruit from vines that are dead or killed by frost.

Those conditions lower the fruit’s acidity, and the standard dose of added acid isn’t enough to make up for it. Green tomatoes are fine; they’re more acidic than ripe ones and can be canned with any of these methods.

Paste tomatoes such as Roma, San Marzano and Amish Paste are the best choice for crushed tomatoes and sauce. They have more flesh and less juice and seed, so they cook down faster and fill jars with less liquid on top.

Slicing tomatoes work too, especially for whole or halved packs; they’ll just give you more juice. A mix of whatever is ripe is perfectly fine.

Budget roughly 3 pounds of tomatoes per quart for whole packs and 2¾ pounds for crushed, or about 1½ pounds (680 g) per pint.

A full canner load of 7 quarts takes around 21 to 22 pounds (9.5 to 10 kg). A 25-pound (11 kg) box from a farm stand makes about 9 quarts of crushed tomatoes, enough for one full canner load and a couple of jars for a second.

Equipment and Ingredients

You don’t need a dedicated canner, but you do need a pot deep enough to keep jars covered by 2 inches (5 cm) of water at a full boil. Most tomato processes run longer than 30 minutes, and that is the depth recommended for those.

A quart jar is about 7 inches (18 cm) tall, so with a rack, 2 inches of water on top and room to boil, you need a pot at least 11 to 12 inches (28 to 30 cm) deep. Measure yours before canning day.

On an electric range, the pot needs a flat bottom and should be no more than 4 inches (10 cm) wider than the burner, or the jars won’t heat evenly.

• Boiling-water canner or deep stockpot with a lid and a rack, so jars don’t sit directly on the hot bottom.
• Canning jars (pint or quart) with no chips or cracks, plus new flat lids and screw bands.
• Jar lifter, which grips a wet, hot jar far more securely than kitchen tongs.
• Wide-mouth canning funnel, headspace tool or ruler, and a clean damp cloth for wiping rims.
• A second large pot for cooking the tomatoes, plus a pot of boiling water and a big bowl of ice water for peeling.

For ingredients, you need only tomatoes, bottled lemon juice or citric acid, and salt if you like it. Salt is for flavor only; add 1 teaspoon (5 ml) per quart or ½ teaspoon per pint, or leave it out. Canning salt dissolves clear, while table salt may cloud the liquid slightly.

Outside the US, where canning is often called bottling, the times in this guide were tested with two-piece mason-style lids.

If you use a different jar system, such as clip-top or rubber-ring jars, follow its maker’s instructions and your local food-safety guidance.

How to Can Crushed Tomatoes Step by Step

Read through all the steps once before you begin. The sequence matters more than speed, and things go smoothly when the canner is hot by the time the tomatoes are ready.

Get the Canner and Jars Ready

1. Wash jars, lids and bands in hot soapy water and rinse them. You don’t need to sterilize jars for tomatoes, because a process of 10 minutes or longer takes care of that inside the canner.
2. Set the rack in the canner, add the jars and fill the canner about halfway with water. Heat it to about 180°F (82°C), just short of a simmer. Keeping the jars in that water keeps them hot, so they won’t crack when hot tomatoes go in.
3. Prepare the lids as the box directs. Many current lids need only a wash, but follow what your brand says.

Peel and Cook the Tomatoes

4. Get a big pot of water boiling hard. Lower in a few tomatoes at a time for 30 to 60 seconds, until the skins split, then move them straight into ice water.

5. Slip off the skins, cut out the cores, and trim away any bruised or discolored spots. Cut the tomatoes into quarters.

6. Put about one-sixth of the quarters in your cooking pot over high heat and crush them with a potato masher or wooden spoon as they go in. They’ll release their juice, which keeps the rest from scorching.

7. Once that first batch boils, add the remaining quarters a handful at a time, stirring constantly. You don’t need to crush these; they’ll soften as they heat.
8. When all the tomatoes are in and boiling, boil them gently for 5 minutes, stirring often so nothing sticks.

Heating that first portion hard and fast is not just a cooking preference. Tomatoes contain an enzyme that breaks down their structure once they’re cut, and it’s what makes some jars separate into a layer of watery liquid under red pulp. Fast heating shuts it down early.

Fill, Seal and Process the Jars

9. Lift a jar from the canner, tip the water back in, and set it on a towel. Add the acid first: 2 tablespoons bottled lemon juice or ½ teaspoon citric acid per quart. Add salt now if you’re using it.

10. Ladle in hot tomatoes through the funnel, leaving ½ inch of headspace. Run a thin plastic spatula or bubble tool around the inside to release trapped air, then top up to ½ inch again if the level drops.
11. Wipe the rim with a clean damp cloth. A seed or a smear of pulp on the rim is one of the most common reasons a lid fails to seal.

12. Center the lid and screw on the band until you feel resistance, then stop. This is called fingertip tight. Over-tightening traps air that needs to escape during processing.
13. Set each filled jar back in the canner with the jar lifter, keeping it upright. Repeat until the canner is loaded.

14. Add hot water as needed until the jars are covered by at least 2 inches. Cover the canner and turn the heat to high.
15. Start the timer only when the water reaches a full, rolling boil: 35 minutes for pints and 45 minutes for quarts, plus any elevation adjustment. Keep it boiling the whole time. If the boil stops at any point, bring it back up and restart the timer from the beginning.

16. When the time is up, turn off the heat and take off the canner lid. Leave the jars in the water for 5 minutes. This short rest lets them settle and reduces liquid seeping out under the lids.
17. Lift the jars straight out, without tilting, onto a towel or rack away from drafts. Leave an inch or two between them.

Safety check: The acid, the headspace, the processing time and the 2 inches of water are what make this safe. Change any of them, or add ingredients not listed here, and the tested time no longer applies.

Canning Whole or Halved Tomatoes Instead

Peel and core the tomatoes exactly as above, then leave them whole or cut them in half. From there, you choose a raw pack or a hot pack.

For a raw pack, put the acid in the jars, fill them with raw tomatoes, and pour boiling water over them, leaving ½ inch of headspace. Start the canner water at about 140°F (60°C) rather than 180°F, since the jars aren’t as hot.

For a hot pack, cover the tomatoes with water in a pot, boil them gently for 5 minutes, and fill hot jars with the tomatoes and their cooking water, again with ½ inch of headspace.

Either way, process pints for 40 minutes and quarts for 45 minutes at up to 1,000 feet.

Hot packing takes a few extra minutes, but it’s worth it. Heating shrinks the fruit and drives out air, so you fit more tomatoes per jar and they won’t float to the top and leave a pale band of liquid at the bottom.

Raw-packed jars almost always float a little. That’s a matter of appearance, not safety.

If you’d rather skip the added water, you can pack peeled raw tomatoes tightly, pressing them until their own juice fills the gaps, or pack them in tomato juice. Both give a richer jar but need 85 minutes for pints or quarts.

After the Canner: Cooling, Checking Seals and Storing

Leave the jars alone for 12 to 24 hours. Don’t tighten the bands, press the lids or tip the jars to look at them. You’ll hear the lids pop down as they cool, which is the vacuum forming, but the real test comes the next day.

Once they’re completely cool, remove the bands and check each lid. A sealed lid is curved slightly downward and doesn’t flex or click when you press the center. Lift the jar gently by the edge of the lid; a good seal holds. If the lid moves, the jar didn’t seal.

For an unsealed jar, you have two choices. Put it in the refrigerator and use it within a few days, or reprocess it within 24 hours: reheat the tomatoes, refill a clean hot jar with a new lid, and run the full processing time again.

Reprocessed tomatoes turn softer, so refrigerating that jar and using it first is usually the easier choice.

Wipe the sealed jars, label them with the contents and date, and store them without bands in a cool, dark, dry place, ideally 50 to 70°F (10 to 21°C).

Keep them away from stoves, furnaces, sunny shelves and anywhere that gets above 95°F (35°C). Plan to use them within a year for the best flavor and color, which also means canning only what you’ll eat in a year.

Troubleshooting Common Problems

What you see	Likely cause	What to do
Tomatoes floating with clear liquid below	Raw pack, or very ripe, juicy fruit	Safe if sealed. Hot pack next time and use paste tomatoes.
Watery layer under the pulp	Enzymes acting before the tomatoes heated up	Safe if sealed. Stir it in when cooking; heat the first batch fast next time.
Liquid lost from the jar during processing	Jars too full, air bubbles left in, or jars cooled too fast	Don’t open to add liquid. If about half is gone, refrigerate and use within 2 to 3 days.
Lid didn’t seal	Food on the rim, a nicked jar, or a band too tight or too loose	Refrigerate and use, or reprocess within 24 hours with a new lid.
Darkened tomatoes at the top of the jar	Air in the headspace	Fine to eat if sealed. Check your headspace next time.
Bulging lid, leaks, mold, spurting or an off smell when opened	Spoilage from underprocessing or a failed seal	Don’t taste it. Discard it where people and animals can’t reach it.

Spoiled tomatoes can smell sour even when the lid still looks sealed, a defect called flat sour that comes from heat-resistant bacteria. If anything about a jar seems wrong, throw it out without tasting.

Shortcuts That Aren’t Safe

You’ll find plenty of tomato-canning methods online that skip a step, and some come with family stories of decades without trouble. Botulism is rare, but it doesn’t announce itself with a bad smell or a bulging lid, so luck isn’t evidence. Skip these:

• Open-kettle canning, where you fill jars with hot tomatoes and let the lids seal on the counter without processing.
• Oven, microwave or dishwasher processing. None of them heats jars evenly or reliably enough.
• Turning jars upside down to seal them instead of processing them.
• Fresh lemon juice or leaving out the acid because your tomatoes taste tart or are an heirloom variety.
• Adding onions, peppers, garlic, celery, oil or flour to a plain tomato recipe. They raise the pH or slow the heat reaching the center of the jar. Season when you open the jar, or use a tested recipe, such as stewed tomatoes or spaghetti sauce, that’s designed for a pressure canner.
• Guessing a processing time for a jar size or style not in a tested recipe.

An atmospheric steam canner is a newer option that is accepted for acidified tomatoes, with conditions: the jars must be preheated, the canner fully vented before timing starts, and the total processing time, including any elevation adjustment, can’t go over 45 minutes.

That rules out the 85-minute whole packs and quarts at higher elevations, and you can’t open it to add water partway through.

Frequently Asked Questions

Do I have to peel tomatoes before canning?

Yes, if you’re using these processing times. Every USDA-tested procedure for whole, halved and crushed tomatoes starts with peeled fruit, so unpeeled jars fall outside what was tested. For sauce, a food mill removes skins and seeds for you.

Can I use a pressure canner for tomatoes?

Yes, and it often gives better flavor and texture, because the process is shorter. You still add the same acid to each jar, since the USDA pressure times for tomatoes were developed with it in the jar.

Use the pressure, time and gauge type listed for your specific tomato style in a tested source such as the National Center for Home Food Preservation.

Can I reuse jars and lids?

You can reuse canning jars for years as long as the rims have no nicks or cracks, and screw bands are fine unless they’re rusted or bent.

Flat lids are single-use, because the sealing compound keeps the dent from its first seal. Mayonnaise-type jars that take a two-piece lid can work for tomatoes, but they’re thinner than canning jars, so expect more breakage and failed seals.

Your First Canning Day

For your first batch, keep it simple: one canner load of crushed tomatoes in quarts, with everything measured and the canner heating before you peel the first tomato.

Once you’ve seen the whole process through and have a shelf of sealed jars, whole packs and sauce feel easy.

Bookmark the processing table, check your elevation, and you’ll have tomatoes for chili and pasta sauce long after the garden is done.

Easy Caramelized Onion Jam Recipe with Balsamic Vinegar

Caramelized onion jam is onions cooked slowly until they turn deep brown, then simmered with sugar and vinegar until a glossy syrup clings to every strand.

It tastes like the best part of French onion soup with a sweet-sour edge, and it makes sharp cheese, burgers and roast pork taste finished.

The ingredient list is short. What decides whether a batch tastes rich or merely sweet and wet is time, a wide pan and knowing when to stop.

Below you’ll find a refrigerator recipe with a clear cue for every stage, fixes for the usual problems, and a straight answer on when a jar can safely live in your pantry.

At a glance

• Makes: about 2 cups (480 ml) from 3 pounds of onions.
• Time: about 1¾ hours, mostly stirring now and then.
• Keeps: up to two weeks in the fridge, or three to four months frozen for best flavor.
• Canning: only with a recipe tested for it. This one is a fridge and freezer jam.

Why Onion Jam Takes Longer Than Most Recipes Say

Onions are about 90% water, and nothing turns brown until most of that water has cooked off. A heap of sliced onions that fills a big skillet to the rim shrinks to about a cereal bowl’s worth by the time it’s deep amber.

Onions contain very little pectin, so the jam won’t set into a gel like strawberry jam. It thickens only as water evaporates and the sugars become concentrated.

That’s why so many recipe timings fall short. “Golden in 10 minutes” describes onions that have softened and colored at the edges.

Properly browning 3 pounds takes 45 minutes to an hour over medium-low heat, and that’s where the flavor comes from.

Onions cooked only until soft make a jam that tastes sugary. Onions taken to a deep chestnut brown make one that tastes roasted and savory, with the sweetness in the background.

Choosing Your Onions, Sweetener and Vinegar

Onions

Yellow storage onions are the best all-round choice. They’re cheap, they brown evenly, and their harsh raw bite turns into exactly the deep, savory sweetness you want.

Sweet onions such as Vidalia, Walla Walla and Maui make a milder jam, but not because they hold more sugar.

They taste sweet because they’re low in the sulfur compounds that make onions sting, which lets their sugar come through; some pungent onions actually contain more.

Sweet onions are juicier too, so plan on a longer cook and a little less added sugar.

Red onions work, though they brown unevenly into a purplish shade and their strands stay firmer. Shallots make a refined small batch if you don’t mind the peeling, and half yellow, half sweet gives a nicely balanced jam.

Sweetener

Onions are naturally sugary, so added sugar is mostly there for body, gloss and balance against the vinegar.

Many published recipes use a cup or more for a couple of pounds of onions, which is usually why people find them cloying.

The recipe below uses ⅓ cup of brown sugar for 3 pounds, which lands on the savory side of sweet. Go up to ½ cup for a jam meant mostly for cheese boards and toast.

Brown sugar adds a gentle molasses note, maple sugar adds warmth, and white sugar tastes cleanest. Maple syrup and honey add liquid, so allow a few extra minutes of reducing.

Vinegar and Fat

Everyday supermarket balsamic gives the darkest, richest jam; keep the pricey aged bottle for the table.

White balsamic keeps the jam golden, while red wine and cider vinegar taste sharper and lighter. Balsamic glaze isn’t a swap, since it’s already reduced and usually sweetened.

For the fat, olive oil is the practical pick. Butter tastes richer but sets firm in the fridge, so a butter-heavy jam has to sit on the counter before it will spread. Swapping a tablespoon of the oil for butter gives you most of the flavor without the stiffness.

Caramelized Onion Jam Recipe

This is a refrigerator and freezer jam. It makes about 2 cups (480 ml) and takes about 1¾ hours, most of it hands-off between stirs.

What You’ll Need

• 3 pounds (1.4 kg) yellow onions, about 6 medium, halved and sliced ¼ inch (6 mm) thick (about 10 cups)
• 3 tablespoons olive oil, or 2 tablespoons oil plus 1 tablespoon butter
• 1 teaspoon kosher salt, plus more to taste
• ⅓ cup (70 g) packed light brown sugar, or up to ½ cup (100 g) for a sweeter jam
• ½ cup (120 ml) balsamic vinegar
• 1 tablespoon red wine or cider vinegar (optional, for extra tang)
• 2 teaspoons fresh thyme leaves, ½ teaspoon dried thyme, or 1 bay leaf
• ½ teaspoon freshly ground black pepper
• Water as needed, about ½ cup (120 ml) in total

You’ll also want the widest heavy pan you own, such as a 12-inch (30 cm) skillet, a sauté pan or a wide Dutch oven. Width matters more than depth, because the onions brown only after their steam escapes.

Stainless steel, enameled cast iron and nonstick all work, but skip uncoated aluminum or copper, which the vinegar can react with and leave a metallic taste.

Step by Step

1. Slice evenly.

Halve each onion through the root, peel it, and cut it root to tip into ¼-inch strips. Even thickness matters more than thinness, because a mix of thin and thick slices scorches and stays raw in the same pan. A food processor’s slicing disc does the job in a minute or two.

2. Soften with salt.

Warm the oil over medium heat, add the onions and salt, and toss to coat. The pan will look overloaded. Cook uncovered, stirring every few minutes, for 10 to 15 minutes, until the onions have released their liquid and collapsed to about half their volume.

3. Brown them slowly.

Lower the heat to medium-low and keep cooking, uncovered, for 40 to 60 minutes. Stir every five minutes or so, and more often as they darken.

When the pan bottom develops a brown crust, splash in a tablespoon or two of water and loosen it with the spoon. Those browned bits are pure flavor, and stirring them back in speeds things up. If the crust turns black or smells acrid, turn the heat down.

The onions are ready when they’re deep amber to chestnut brown, soft enough to crush against the pan, and taste sweet with no raw bite.

4. Add the sugar and vinegar.

Stir in the brown sugar until it melts, then add the balsamic, the extra vinegar if you’re using it, the thyme or bay leaf and the pepper. Keep your face back for a moment, as hot vinegar gives off a sharp steam.

Simmer over medium-low, stirring often, for 15 to 25 minutes. Balsamic turns the mixture very dark, so judge it by texture rather than color.

5. Check the set.

Drag a spoon across the bottom of the pan. When the path it leaves stays open for a couple of seconds before the syrup runs back together, it’s done.

It should still look slightly loose, because it thickens a lot as it cools. If you’re unsure, chill a spoonful on a cold plate for a minute and check it.

6. Season and store.

Remove the bay leaf, taste, and add salt or a few drops of vinegar if the jam tastes flat. Cool it, spoon it into clean jars or containers, cover and refrigerate.

A juicier batch of onions or a shorter reduction gives a little more jam, with a looser texture.

Faster, Bigger and Hands-Off Batches

• In the oven.

After step 2, slide the uncovered pot into the oven at 300°F (150°C) and stir about every half hour. Browning takes roughly 30 minutes longer than on the stove but needs far less watching. Finish the last steps on the stovetop.

• In a slow cooker.

On low, with the lid slightly ajar, a slow cooker browns onions gradually over most of a day. It can’t reduce the syrup well, so finish in a wide pan.

• Doubling up.

Don’t simply pile twice the onions into the same pot. Only the surface lets steam escape, so a deep pan can nearly double the browning time and leave the bottom layer stewing. Brown the onions in two pans, then combine them for the sugar and vinegar stage.

• The 25-minute shortcut.

Some recipes cook the onions only until golden, then melt sugar over them without stirring and caramelize it on high heat. You get a quick, sweet burger topping with less roasted depth.

Fixing Common Problems

Problem	Likely cause	Fix
Onions still pale and wet after an hour	Lid on, heat too low, or pan too full	Uncover, raise the heat to medium, and spread them into a wider pan or two pans
Bitter, scorched bits	Heat too high or too little stirring	Lower the heat, deglaze with water, and pick out anything black
Runny once cool	Not reduced far enough	Simmer a few minutes more, uncovered, and recheck the spoon test
Stiff or gluey in the jar	Reduced too far	Stir in 1 to 2 tablespoons of warm water or vinegar
Too sweet	Too much sugar, or very sweet onions	Add vinegar a teaspoon at a time, plus pepper and a pinch of salt
Too sharp or sour	Strong vinegar or a short reduction	Simmer a little longer or add a spoonful of sugar; it also mellows overnight
Hard to spread from the fridge	Butter firming up as it chills	Let it stand 15 to 20 minutes, or use all oil next time

Flavor Variations

Add these with the sugar and vinegar unless noted.

• Herby or warm-spiced: a sprig of rosemary or sage (removed before jarring), or a pinch of cinnamon or allspice for pork and turkey.
• Smoky: ½ teaspoon smoked paprika or smoked salt, or grill halved onions before slicing them.
• Spicy: a pinch of red pepper flakes or a finely chopped fresh chile.
• Boozy: 2 to 3 tablespoons of bourbon, port or red wine, simmered with the vinegar.
• Soy and spice: rice vinegar in place of balsamic, a tablespoon of soy sauce, and cumin and coriander seeds toasted in the oil first. Excellent on rice bowls and fried eggs.
• Garlic or bacon: roasted garlic or crumbled cooked bacon stirred in at the end. Both shorten the fridge life, as explained below.

How Long Onion Jam Keeps in the Fridge and Freezer

Nobody has lab-tested how long homemade fridge onion jam lasts, and published advice ranges from four days to several months.

The sugar and vinegar slow spoilage but don’t make the jam shelf-stable, so treat these as sensible limits rather than guarantees:

• This recipe, or any onion jam with a generous amount of sugar and vinegar: up to two weeks in a clean, covered jar.
• A barely sweetened batch with only a splash of vinegar, or any version with bacon or garlic stirred in: that’s closer to cooked leftovers, so follow the USDA rule for leftovers and finish it within three to four days.

Keep it at 40°F (4°C) or below, use a clean spoon every time, and discard any jar that shows mold, fizzing or an off smell.

For a big batch, the freezer is the easiest answer. Spoon the cooled jam into small containers, leaving ½ inch (1 cm) of headspace in glass, or freeze it in an ice cube tray and bag the cubes.

Frozen food stays safe indefinitely, but the jam tastes best within three to four months. Thaw it in the fridge, or drop a cube straight into a pan sauce or soup.

Can You Can Caramelized Onion Jam?

Only with a recipe that has been tested for canning, and the usual buttery, balsamic caramelized onion jam isn’t one. Onions are a low-acid vegetable, with a pH of roughly 5.3 to 5.8.

Boiling-water canning is safe only for foods at pH 4.6 or below, where botulism bacteria can’t grow, which is why plain onions have to be pressure canned.

An onion preserve can go in a boiling-water canner only when the recipe adds enough acid to bring the whole jar below that line, and the only way to know a recipe does that is testing at those exact proportions.

Plenty of onion jam recipes print water-bath times anyway, sometimes citing a single pH reading as proof.

One home reading doesn’t replace a tested recipe, and many of these recipes cook the onions in butter or oil, which Penn State Extension warns can shield bacteria from the heat of processing.

If a recipe doesn’t name the tested source behind its canning time, keep it in the fridge.

For jars you can keep in the pantry, choose an onion preserve developed for home canning and follow it exactly:

• Ball’s Red Onion and Port Jam: red onions simmered with port and red wine vinegar, then set with low-sugar pectin.
• Pomona’s Pectin’s Caramelized Onion-Maple Jam: onions caramelized without any fat precisely so the jam can be canned, then cooked with apple cider, cider vinegar and maple syrup and set with Pomona’s pectin.
• Onion Relish from the University of Georgia’s So Easy to Preserve: a simple sweet-sour relish of onions, vinegar, sugar and mustard seed.

Once you’re working from a tested recipe, these rules keep it safe:

• Use the type and acidity of vinegar the recipe specifies (usually 5%), measure it exactly, and use bottled lemon juice where it’s called for.
• Don’t add butter, oil, bacon, garlic, fresh chiles or extra onions. Each one changes the acidity or the heat penetration the recipe was tested at.
• Process for the full time, with the altitude adjustment the recipe gives, and refrigerate any jar that doesn’t seal.
• Don’t reach for a pressure canner as a workaround. There’s no tested pressure-canning process for onion jam.
• Skip shortcuts such as sealing hot jam in hot jars without processing, or heating filled jars in the oven. The National Center for Home Food Preservation advises against both.
• Don’t boil the lids. Current Ball directions simply have you wash them in warm, soapy water, and Bernardin specifically advises against preheating them.

Ways to Use Onion Jam

Serve it at room temperature, since cold mutes the flavor, but set out only what you’ll use and get leftovers back in the fridge within two hours.

Its natural partner is cheese: sharp cheddar, aged Gouda, blue cheese and goat cheese all welcome a spoonful.

For an easy appetizer, spread it over a wheel of brie, wrap it in puff pastry and bake, or pour it over a block of cream cheese and set out crackers.

It’s just as useful in everyday cooking:

• On burgers, brats and hot dogs, in place of raw onion
• Layered into a grilled cheese made with Gruyère or a sharp cheddar
• As a pizza or flatbread base instead of tomato sauce, topped with goat cheese and arugula
• As a glaze for salmon, pork tenderloin or chicken thighs, brushed on in the last 10 minutes so the sugar doesn’t burn
• In a quick pan sauce: after searing pork chops or steak, add a splash of stock and a spoonful of jam, then scrape and simmer
• Stirred into mashed potatoes, mac and cheese or a quiche filling

Onion Jam FAQ

Do you need pectin to make onion jam?

No. Onion jam thickens by reduction alone. Pectin shows up only in some tested canning recipes, such as Ball’s and Pomona’s, where it’s part of the tested formula and gives a set with less cooking down.

Can I make onion jam with less sugar or a sugar substitute?

Yes, for a fridge or freezer batch. Cut the sugar to a tablespoon or two and you’ll get something closer to deeply caramelized onions, looser and more savory, with the shorter fridge life of leftovers.

Erythritol or monk fruit sweeteners work for flavor but add less body. In a canning recipe, change the sweetener only if the recipe itself says you can.

How much jam does a pound of onions make?

About ⅔ cup with this recipe, and a pound of onions is 3 to 4 cups sliced. For three 8-ounce (240 ml) gift jars, start with about 4½ pounds (2 kg) and brown them in two pans.

Label fridge jam clearly with “keep refrigerated” and the date. If you want gifts that can sit on a shelf, make a tested canning recipe instead.

Is onion jam the same as onion relish or onion marmalade?

Mostly, yes. What Americans call onion jam is often sold as onion relish in Australia or onion marmalade in the UK, while chutneys tend to be chunkier, with fruit and more spice. A recipe’s name never tells you whether it’s safe to can.

Your First Batch

Give the browning its full hour and pull the jam off the heat while it still looks a little loose, and your first batch will show you how sweet and how sharp you like it.

Next time, adjust the sugar and vinegar to match, try the smoky or warm-spiced variation, or brown a double batch in two pans and freeze half in cubes.

How to Can Peaches: Safe Step-by-Step Guide (Hot or Raw)

Canning peaches is one of the friendliest ways to start water bath canning. Yellow peaches are acidic enough to process in a pot of boiling water, they need no added lemon juice, and the only ingredients are fruit and a syrup as sweet or as plain as you like.

The catch is that a lot of peach recipes in circulation get the processing time wrong, usually by mixing up raw and hot packs.

This guide gives you the tested method, the right time for your jar size and altitude, and the fixes for floating, browning and leaking jars.

At a glance

• Peaches: yellow-fleshed only, ripe but still firm. Never white or donut peaches.
• How many: about 17½ pounds (7.9 kg) for 7 quarts, or 11 pounds (5 kg) for 9 pints.
• Method: boiling water canner; a pressure canner is optional, not required.
• Headspace: ½ inch (1.25 cm).
• Time at 0 to 1,000 feet (0 to 305 m): hot pack 20 minutes for pints, 25 for quarts. Raw pack 25 for pints, 30 for quarts. Add time at higher altitudes.

Start With the Right Peaches

Yellow Flesh Only

Every tested canning process for peaches was developed with yellow-fleshed fruit, which typically runs from about pH 3.3 to 4.0. Boiling water canning is only safe for foods below pH 4.6.

Some white-fleshed varieties come in above that line, and the National Center for Home Food Preservation (NCHFP) says there is currently no tested pressure process and no researched way to acidify white peaches for the water bath.

You’ll find blogs that list a white variety such as Southern Pearl among “canning peaches,” or suggest a spoonful of lemon juice will fix the acidity.

Neither is backed by testing. Flat donut (Saturn) peaches are usually white-fleshed, so treat them the same way. Freeze or dry white peaches instead.

Freestone or Clingstone

Freestone peaches let go of the pit when you twist the halves apart, which makes them the easy choice for halves and big batches.

Clingstone flesh grips the pit, so you end up cutting slices off the stone. Many canners swear clings stay firmer and taste better, and they can just as safely; plan on slices rather than neat halves.

In many growing regions the earliest peaches of the season are clings and the freestones follow a few weeks later, so ask the grower which you’re buying.

Varieties extension services recommend for canning include Elberta, Redhaven, Cresthaven, Sunhigh, Loring and Glenglo, but any good yellow eating peach from your area will work.

Ripe but Still Firm

Look at the background color, not the red blush. It should be yellow or cream with no green around the stem. Pick fruit that gives slightly when you press near the stem but doesn’t dent.

Overripe peaches turn to mush and float in the jar; hard green ones are miserable to peel and won’t ripen properly.

Peaches sold for canning are often picked firm. Spread them out in a single layer at room temperature, or close a few in a loose paper bag, and check them every day. They usually come ready in 2 to 3 days, and not all at once, so can the ripest ones first.

Soft or bruised fruit is better turned into jam or peach butter than squeezed into jars.

How Many to Buy

Plan on an average of 2½ pounds (1.1 kg) of whole peaches per quart jar and about 1¼ pounds (570 g) per pint, a little less for halves, which leave gaps, and a little more for slices, which pack tighter.

A full bushel weighs 48 pounds (22 kg) and gives 16 to 24 quarts. A 25-pound (11 kg) box, the size many peach trucks and orchards sell, fills roughly 10 quarts. Buy a few extra to cover bruises and the fruit you’ll eat while you work.

What You Need

• A boiling water canner, or any deep pot with a rack.

It has to hold enough water to cover the jars by 1 to 2 inches (2.5 to 5 cm) while boiling. A rack, or a layer of canning rings tied together, keeps jars off the hot bottom.

On an electric range, use a flat-bottomed canner no more than 4 inches (10 cm) wider than the burner, and check your range maker’s advice for a glass top.

• Pint or quart canning jars.

Peach times were tested in pints and quarts only, so skip half-gallon jars and odd sizes. Check the rims for nicks.

Wash the jars, and keep them hot until you fill them. Anything processed 10 minutes or more needs no presterilizing, so a clean jar is enough.

• New flat lids and clean bands.

Prepare the lids the way the manufacturer says; most current lids no longer need simmering.

• Small tools

A jar lifter, a wide-mouth funnel, a plastic bubble remover or thin spatula, a ladle and slotted spoon, and towels for the counter.

• For prep:

A big pot for blanching, a bowl of ice water and a large bowl for the anti-browning soak.

An atmospheric steam canner also works for peaches, with the same times as a water bath, as long as you follow its directions: vent all the air out before you start timing, keep it at full steam the whole time, fill preheated jars and load them promptly, and keep the total time at 45 minutes or less.

Every peach time, even with the altitude adjustment, fits under that limit.

Choose Your Canning Liquid

Sugar in canned fruit is there for quality, not safety. It helps peaches hold their color, shape and flavor, but the heat of processing is what preserves them, so you can can peaches in plain water if you want.

The trade-off is real: water-packed peaches come out softer and paler and taste washed-out after a few months.

“Light syrup” means wildly different things from one recipe to the next, anywhere from about 10 to 33 percent sugar. These are the NCHFP measurements, with the sugar percentage so you can compare:

Syrup	Sugar	For 9 pints	For 7 quarts
Very light	about 10%	6½ cups water + ¾ cup sugar	10½ cups water + 1¼ cups sugar
Light	about 20%	5¾ cups water + 1½ cups sugar	9 cups water + 2¼ cups sugar
Medium	about 30%	5¼ cups water + 2¼ cups sugar	8¼ cups water + 3¾ cups sugar

A US cup is 240 ml and a cup of sugar weighs about 200 g. Very light syrup comes close to the natural sugar level of the fruit itself.

Light is the usual choice, and medium tastes like dessert. Heavier syrups aren’t unsafe, but they make fruit float more.

The 9-pint batch also covers a 4-quart load, and hot packs use less syrup than raw packs because the fruit releases juice as it heats.

Other liquids work too:

• Unsweetened apple or white grape juice, straight or cut with water, adds sweetness without refined sugar.
• NCHFP’s guidance is to replace up to half the sugar with a mild-flavored honey. Honey is sweeter than sugar, so you need a little less of it. It doesn’t make the jars any safer than sugar does.
• Sugar substitutes. Research at the University of Georgia found Splenda in a full- or half-strength medium syrup worked for peaches. Aspartame breaks down when heated and saccharin can turn bitter. Stevia hasn’t been tested, so it’s simpler to sweeten at the table.

For spiced peaches, add whole spices to each jar: a cinnamon stick and a few cloves or allspice berries. Ground spices turn the syrup cloudy. Leave untested additions such as coconut milk, other fruits, fresh herbs or a peach pit out of the jar.

Hot Pack or Raw Pack?

This is the choice most peach recipes get wrong. The pack style describes the fruit, not the liquid:

• Hot pack: you heat the peaches in boiling syrup, juice or water, then fill the jars with hot fruit and liquid.
• Raw pack: you put uncooked peaches in the jars and pour boiling liquid over them.

Pouring boiling syrup over raw slices is still a raw pack, and it needs 5 more minutes in the canner than a hot pack.

You’ll often see recipes that raw-pack the fruit but list the hot-pack times of 20 and 25 minutes, or one time for both jar sizes.

Those jars are underprocessed. If a recipe doesn’t say which pack it uses, or its times don’t match the chart below, use the chart.

Both packs are safe when you use the right time, but hot packing gives a noticeably better jar.

Heating drives air out of the fruit, so the peaches shrink before they go in rather than in the canner. You fit more fruit per jar, it floats less, it loses less liquid and it keeps its color longer.

NCHFP flatly says raw-packed peaches are poor quality. Ball goes further and says to hot pack whenever you use water or juice.

Raw packing does save a little handling, and it’s fine for a small batch you’ll eat within a few months. For anything headed to the back of the pantry, hot pack.

How to Can Peaches Step by Step

This recipe makes a full canner load of 7 quarts in light syrup, hot packed. For 9 pints, use 11 pounds of peaches and the 9-pint syrup amounts.

Ingredients

• 17½ pounds (7.9 kg) ripe, firm yellow peaches
• 9 cups (2.1 L) water and 2¼ cups (450 g) sugar for light syrup, or another liquid from the table above
• Anti-browning treatment: 1 teaspoon (3,000 mg) ascorbic acid powder, or six crushed 500-mg vitamin C tablets, dissolved in 1 gallon (3.8 L) cold water

Plain lemon water helps too, but ascorbic acid works better, and citric acid powder on its own does little to stop browning.

Steps

1. Wash the jars and keep them hot in the canner or a sink of hot water. Put the rack in the canner, fill it about halfway and heat the water to 180°F (82°C). Prepare the lids.
2. Mix the anti-browning solution in a large bowl. Make the syrup in a wide pot by bringing the water and sugar to a boil.
3. Heat a second large pot of water until it boils. Lower in a few peaches at a time for 30 to 60 seconds, until the skins loosen, then move them straight into ice water. If the skins still cling after a minute, the fruit isn’t ripe enough; leaving it in longer just cooks the outside.

4. Slip off the skins. Cut each peach in half along the seam, twist out the pit and scrape away any loose red fibers in the cavity, which darken in storage. Leave them as halves or cut thick slices, and drop the pieces into the anti-browning solution as you go.

5. Drain the peaches and add them to the boiling syrup, one layer deep so the syrup covers them. Bring the syrup back to a boil.

6. Pack the hot fruit into a hot jar with a slotted spoon, halves cut side down in overlapping layers. Ladle in hot syrup to leave ½ inch (1.25 cm) of headspace.

7. Slide a plastic bubble remover around the inside of the jar, pressing gently against the fruit, then top up the syrup to ½ inch again.

8. Wipe the rim with a clean, damp cloth, center a lid on top and screw the band on fingertip tight, just until you feel resistance. Set the jar in the canner and fill the rest the same way.
9. Add hot water as needed so it covers the jars by at least 1 inch (2.5 cm), or 2 inches (5 cm) for any process longer than 30 minutes. Put the lid on and set the burner to high.

10. Begin timing when the water reaches a hard, rolling boil: 20 minutes for pints and 25 for quarts at 0 to 1,000 feet. If the boil stops at any point, bring it back and start the full time again.
11. When the time is up, turn off the heat, take off the lid and leave the jars in the water for 5 minutes. This short rest cuts down on syrup leaking out.
12. Lift the jars straight up without tilting them and set them on a towel, an inch or so apart, away from drafts.

For a raw pack, skip step 5. Pack the drained raw peaches into hot jars, pour in boiling syrup to ½ inch, and heat the canner water to only 140°F (60°C) before loading the jars. Then process 25 minutes for pints and 30 for quarts.

Processing Times by Altitude

Water boils at a lower temperature the higher you live, so jars need longer in the canner. These are the NCHFP times for peach halves or slices in a boiling water or steam canner:

Altitude	Hot pack (pints / quarts)	Raw pack (pints / quarts)
0–1,000 ft (0–305 m)	20 / 25 min	25 / 30 min
1,001–3,000 ft (306–914 m)	25 / 30 min	30 / 35 min
3,001–6,000 ft (915–1,829 m)	30 / 35 min	35 / 40 min
Above 6,000 ft (1,829 m)	35 / 40 min	40 / 45 min

If you’re not sure of your elevation, look it up. The adjustment is 5 minutes per band, not the 1 minute per 1,000 feet you’ll see in some recipes; that rule belongs to sterilizing empty jars for jam.

Pressure canning is allowed but gains you nothing for peaches except softer fruit. If you prefer it, process hot- or raw-packed pints or quarts for 10 minutes after venting the canner for 10 minutes.

In a weighted-gauge canner use 5 psi (34 kPa) up to 1,000 feet and 10 psi (69 kPa) above that.

In a dial-gauge canner use 6 psi (41 kPa) up to 2,000 feet (610 m), 7 psi (48 kPa) to 4,000 feet (1,219 m), 8 psi (55 kPa) to 6,000 feet and 9 psi (62 kPa) to 8,000 feet (2,438 m).

Times were developed in US pints (473 ml) and quarts (946 ml). Metric 500 ml and 1-liter jars are commonly processed on the pint and quart times, but a liter is a little larger than a US quart, so use true quart jars where you can.

In New Zealand and Australia, where canning is often called bottling, the older overflow method is no substitute for processing.

Cooling, Checking Seals and Storing

Leave the jars alone to cool for 12 to 24 hours. Don’t retighten the bands, even if they feel loose; that can break the seal as it forms. You’ll often hear lids ping as they seal, but a quiet jar isn’t necessarily a failure.

Once the jars are cool, take off the bands and press the center of each lid. A sealed lid is slightly concave and doesn’t move. If it flexes or pops back, the jar didn’t seal, and you have three choices:

• Refrigerate it and eat the peaches within about a week.
• Freeze the contents in a freezer container, leaving 1 inch of headspace.
• Reprocess within 24 hours. Check the rim for nicks, put on a new lid and run the full time again. It’s safe but leaves the peaches noticeably softer, which is why the first two options are usually better.

Wash any sticky syrup off the sealed jars, since residue can grow mold outside the jar, then label and date them.

Store them without bands in a cool, dark, dry place, ideally between 50 and 70°F (10 and 21°C). Never keep them above 95°F (35°C), near a furnace or stove, or in direct sun.

For best quality, eat home-canned peaches within a year. Sealed jars stay safe longer, but color, flavor and texture slowly fade, and faster in a warm room.

Before opening any jar, check it. Throw it out without tasting if the lid bulges or has come loose, liquid has leaked, there’s mold, the contents spurt or fizz when opened, or anything smells off.

Once opened, keep the jar in the refrigerator and finish it within about a week.

Troubleshooting Common Problems

• Peaches floating at the top.

Air in the fruit, loose packing, overripe peaches or a heavy syrup. It’s cosmetic. Next time hot pack, pack the jars snugly without crushing, and use a light or medium syrup.

• Syrup leaked out or the level dropped.

This is called siphoning. Common causes are trapped air, overfilled jars, bands that are too loose or too tight, too little water over the jars, and lifting jars out without the 5-minute rest.

A sealed jar is still safe; don’t open it to add liquid. Raw-packed jars look noticeably lower after cooling because the fruit shrinks.

• Fruit dark at the top.

Peaches above the liquid oxidize. It’s harmless, so eat those jars first. Removing bubbles and keeping the fruit covered prevents it.

• Pink, blue or red tints.

A natural, harmless reaction in some peaches during heating. Minerals in hard water or in iron, copper or zinc pans can also discolor fruit, so use soft water if yours is hard.

• Cloudy syrup.

Usually hard-water minerals, undissolved sugar, ground spices or bits of overripe fruit. If the cloudiness comes with a broken seal, bubbling or an off smell, it’s spoilage, so discard the jar.

• Mushy peaches.

Overripe fruit, blanching too long or slices cut too thin. Pressure canning softens them further.

• A jar cracked in the canner.

Usually a cold jar meeting hot water, a jar sitting on the bottom of the pot without a rack, a nicked jar, or a band screwed on too hard.

Shortcuts to Avoid

Old family methods and viral recipes keep these alive, but none of them reliably makes peaches shelf-stable:

• Oven canning, open-kettle canning and turning hot jars upside down. A jar that seals is not the same as a jar that’s been heated through. NCHFP specifically warns against processing jars in ovens, microwaves or dishwashers.
• Bringing a pressure canner to 5 pounds and switching it off. No tested process works that way; either pressure-can for the full 10 minutes or use a water bath.

Frequently Asked Questions

Do I need to add lemon juice when canning peaches?

No. Yellow peaches carry enough natural acid, so lemon juice in the jar is only for flavor or color. Use it, or ascorbic acid, in the soaking water to stop browning while you prepare the fruit.

Peach pie filling is different: its tested recipe calls for bottled lemon juice, and the amount must not be cut.

Can I can peaches with the skins on?

It isn’t recommended. The tested process starts with peeled fruit, so skin-on jars fall outside it. Peach skins also turn tough or slimy in the jar. A 30- to 60-second blanch makes peeling quick.

Can I can just a few jars?

Yes. Use the same processing time for two jars as for seven, as long as the water still covers them by 1 to 2 inches. The 9-pint syrup batch is enough for up to 4 quarts, and you can halve it for fewer.

Before You Start

If this is your first batch, keep it simple: yellow freestone peaches, light syrup, hot pack, and the time from the chart for your altitude and jar size. Start with half a canner load so the peeling doesn’t wear you out.

Once those jars have sealed and you’ve opened one in January, you’ll know exactly how sweet you like them, and the next batch can be bigger.
