Canning Jam and Jelly: Why canning is worth the effort

Canning & Preserving

While you can easily preserve jam and jelly by pouring them hot into sterilized jars, canning (also called “water bath canning”) offers several important advantages. The good news is, you don’t always need a special canning kettle — an ordinary large pot works just fine!


What’s the Difference Between Preserving and Canning?

When you preserve, you pour hot jam or jelly into clean jars and seal them tightly with a lid. Because jam contains a lot of sugar, that sugar acts as a natural preservative.

When you can, you heat the filled jars again in a hot water bath. This extra heating kills any remaining bacteria and creates a stronger vacuum seal. That means a longer shelf life — even for low-sugar jams.


Why Should You Can Jam and Jelly?

There are several good reasons why canning is worth the effort:

  • Lower sugar content: You can safely preserve jam with less sugar.
  • No need to sterilize jars beforehand: The canning process takes care of that.
  • Better vacuum seal: Heating pushes out trapped air, sealing jars more firmly.

Canning also gives you peace of mind: your jars are tightly sealed and safe to store for years. And you’ll almost never have to deal with mold again!


Jam and Jelly with Less (or No) Sugar

Sugar is an excellent preservative — but only when used in sufficient amounts. If you prefer a lower ratio, such as two parts fruit to one part sugar, your jam will generally keep for about six months. Want to store it much longer? Canning is the answer. Properly canned jam can stay good for several years when unopened.

If you’re using no sugar at all, or sweeteners like honey or stevia, canning becomes essential for safe preservation.


No Need to Sterilize Jars

If you plan to can your jam, there’s no need to sterilize jars in boiling water. Just make sure they’re clean — run them through the dishwasher or wash them in hot water with a bit of dish soap. Place the jars and lids on a clean towel and fill them with hot jam.

Since the jars will be heated again during canning, they’ll be automatically sterilized. That means no more fishing jars out of boiling water — saving time and reducing the risk of burns.


Better Vacuum = Longer Shelf Life

Anyone who’s made jam before knows that satisfying “pop” sound when the lids seal as the jam cools. Sometimes, though, that doesn’t happen. By canning the jars, you reheat the jam so trapped air escapes and a strong vacuum forms, extending the shelf life.

If you prefer the traditional method, you can simply re-can any jars that didn’t seal properly. If a jar still doesn’t seal after canning, there’s likely an issue with the lid or rim — check and replace it if needed.


What You Need for Canning Jam

  • A canning kettle or large stockpot
  • A thermometer
  • A kitchen towel or canning rack

Canning Jam: Step by Step

  1. Fill a large pot with water and place the filled jars inside.
  2. Make sure the jars don’t touch each other — you can place a kitchen towel on the bottom to prevent rattling.
  3. Heat the water to 90°C (195°F) and maintain that temperature for 15 minutes.
  4. Carefully remove the jars and let them cool completely.
  5. Once cool, check if the lids are concave — that means they’ve sealed properly.

If a jar hasn’t sealed, store it in the refrigerator and use it first.


Canning Without a Canning Kettle

No canning kettle? No problem! A large stockpot or soup pot works just as well, as long as you can maintain the correct temperature. A digital cooking thermometer helps ensure accuracy.

Some people even can in the oven: place the jars in a baking dish with about 1 inch (2.5 cm) of water and heat at 265°F (130°C) for 30 minutes.


Shelf Life and Storage

Properly canned jam keeps for at least two years when stored in a cool, dry, and dark place. Always check the vacuum before opening — a good seal means the lid is slightly concave.

If you notice mold, bubbles, or an unusual smell, it’s safest to discard the contents.

Waterbath Canning and Botulism

Botulism is a rare but serious illness caused by Clostridium botulinum. Thankfully, we don’t need to worry about it when making jam or jelly. The bacteria can’t survive in acidic environments, and fruit naturally contains plenty of fruit acids — even if they’re masked by sugar.

So as long as you work cleanly and seal your jars properly, the risk of botulism in fruit preserves is virtually zero.

For more information, see the official CDC page on botulism.


Why Wanning is Worth the Effort

Canning takes just a little extra time but pays off in many ways: safety, sustainability, and the deep satisfaction of a pantry filled with homemade preserves. Your jam stays good for years, even with less sugar — all without artificial additives.

Canning Applesauce: From Harvest to Pantry

Canning & Preserving

When autumn arrives and the days grow shorter, I know it’s the start of one of the busiest—and most rewarding—times in our garden: apple harvest season. Our apple trees are only a few years old, but the semi-dwarf varieties already yield a surprisingly rich harvest. It never stops feeling special to see branches heavy with fruit you’ve grown yourself.

With so many apples, the big question is: what do you do with them all? Some apples keep well for months, others need to be used right away. In our home, there are a few recipes I make every year: apple juice, jelly, syrup, and of course applesauce—a true family favorite.


A Family Tradition

Canning fruits and vegetables isn’t something I invented myself—it runs in the family. My grandmother had a large vegetable garden and a cellar lined with jars she had filled herself. From beans to peaches, jams to applesauce—everything was neatly organized, ready to enjoy during the winter months.

That pantry was more than just convenient; it gave a sense of security and pride. From my very first vegetable patch, I knew I wanted to carry on that tradition. Now our cellar shelves, too, are stocked each year with jars of applesauce and other homemade preserves.


Why Can Applesauce?

Applesauce is one of the easiest ways to process and preserve apples. It requires only a few ingredients, it’s simple to make, and everyone loves it. By canning, you extend its shelf life considerably—properly canned applesauce will keep for at least two years, though in our house it rarely lasts that long.

Even apples with blemishes are perfectly fine, as long as you cut away the bad spots. I usually save windfall apples for juice or jelly (since you don’t need to peel them), while for applesauce I prefer larger apples—it goes faster.


The Joy of an Apple Peeler

Maybe you’ve seen one: a small metal tool you clamp onto the table, stick an apple on, and turn the handle. As you rotate, the blade peels the apple in one smooth spiral. I use it every year, and it saves me hours of work—especially when I’m making a ten-liter (2.5-gallon) batch at once.

The kids love to help, too. They turn the handle with enthusiasm, watching the peel fall off in one long ribbon. Making applesauce turns into a fun family activity.

No rush

With five applesauce fans at home, I know I need to prepare quite a bit to get us through the winter. I work in batches: every week during harvest season, a large pot of apples goes on the stove. I start with the apples that have spots, since they spoil the fastest, and leave the firmer varieties for later—they can be stored for weeks, even months, in a cool place. This way, the work spreads itself out.


Ingredients for Homemade Applesauce

Yields about 3 quarts (3 liters)

  • 6 ½ pounds apples (3 kg)
  • 2 cups water (500 ml)
  • 1 to 1 ½ cups sugar (200–300 g), to taste
  • Sterilized canning jars, lids, and rings

I like a touch of sweetness, so I always add a bit of sugar. It isn’t necessary for preservation—the canning process takes care of that—but I prefer the flavor. If you want a sugar-free version, that works perfectly too, especially with naturally sweet apples like Jonagold or Gala.

Step-by-Step: How to Make and Can Applesauce

1. Prepare the Apples

Peel the apples and remove the cores. Cut into chunks—the smaller the pieces, the faster they cook.

2. Cook the Apples

Place the apple chunks and water into a large pot. Bring to a gentle boil. The water prevents the apples from burning.

3. Make the Sauce

Simmer until the apples fall apart. Stir occasionally to prevent sticking. Puree for a smooth sauce, or mash lightly for a chunkier texture.

4. Season to Taste

Taste the applesauce and add sugar as needed. I usually keep it simple, but you can add spices such as cinnamon, ginger, or vanilla for variety.

5. Canning

Fill sterilized jars with the hot applesauce. Wipe the rims, seal, and process for 30 minutes in a water bath canner at 195°F (90°C).

6. Storing

Let the jars cool undisturbed, label with the date, and store in a dark, cool place. Properly canned applesauce will keep for up to two years.

Extra Tips for the Best Applesauce

  • Choosing apples: Use cooking apples that break down easily. A mix of varieties usually gives the best balance of sweet and tart.
  • Sugar or no sugar: Not required for safety—add only to taste. Always sample before deciding how much to use.
  • Spices: Keep it pure, or add cinnamon, clove, or ginger for a festive twist.
  • Sterilization: Make sure jars, lids, and rings are thoroughly sterilized for safety and shelf life.

Bonus: Making Apple Juice from Applesauce

Some apples release a lot of juice. After cooking, you can strain the sauce through a cheesecloth to separate out apple juice. Bottle the juice separately—it’s delicious as-is or concentrated into syrup.

Since the juice is no longer boiling when it drains from the applesauce, you’ll need to process it: either bring it briefly to a boil and bottle in sterilized jars, or can it in bottles for 30 minutes at 195°F (90°C).

This “fresh-pressed” apple juice is wonderful on a cold winter evening, especially with a bit of cinnamon or ginger. It captures the cozy flavors of autumn in a glass.


Creative Ways to Use Applesauce

At our house, applesauce is a classic side dish with roasted chicken or sausages. The sweetness balances savory flavors perfectly. But there are many other uses:

  • Baking: Use as a filling for turnovers or pies.
  • Granola: Replace part of the honey with applesauce for a healthier binder. Add ginger and cinnamon for a cozy fall version.
  • As a topping: Serve warm applesauce over pancakes or waffles.
  • With winter meals: Add a spoonful to hearty dishes like stews or mashed vegetables—it rounds out the flavors beautifully.

Homemade Applesauce: Small Effort, Big Reward

What I love most about making applesauce is how little effort it takes compared to the reward. In just a few hours, you create jars that last for months. And honestly, there’s nothing more satisfying than seeing your own jars lined up in the pantry. Just like my grandmother, I feel a sense of richness and connection to the garden and the season every time I open one.
