Is It Safe To Freeze Jam? Read Here!

Can You Freeze Jam?

Yes, you can. If you want to freeze jam, you need to put it into the freezer for at least two hours. This will allow the jam to solidify and become easier to handle. Once it has frozen, you can transfer it into a container or jar.

Jam is a delicious spreadable fruit preserve. The name comes from the French word jambon meaning ham. It’s usually made from strawberries, raspberries, blackcurrants, blueberries, redcurrants, gooseberries, and apples.

What is a jam made of?

The main ingredients in jams are sugar, pectin (a natural thickener), acidity, and water. Sugar is added to the mix to help preserve the product. 

Pectin is an enzyme that helps thicken the mixture. Acidity is used to balance out the sweetness of the jam. Water is needed to keep the mixture liquid enough not to harden too much when stored.

Homemade Jam Recipe:


  • 1 cup sugar
  • 2 cups fresh berries
  • Juice of 1 lemon
  • 3 tablespoons cornstarch


  • Place all ingredients into a pot over medium heat.
  • Bring to a boil, then reduce heat and simmer until it reaches 220 degrees Fahrenheit on a candy thermometer.
  • Stir often to prevent sticking.
  • When done, pour into sterilized jars and seal.
  • Store in refrigerator for up to 6 months.

How to Freeze Jams?

Most people know that freezing food can be a good way to preserve it. But do you know how to freeze fruit jams? Read on for the answer to this question.


STEP 1 Measure your jam jar. 

The moment you have enough space in a freezer, you’re ready to start freezing your jam. An easy way to determine how much room you need is to measure the inside diameter of the jar, then divide that number by the height of the jar. For example, if the inside diameter of your jar is 7/8 inches and its height is 1 inch, you need a total of 8/9 inches of space in the freezer.

STEP 2 Place the jar in the freezer. 

If you’ve chosen to freeze your jam in a plastic or glass container, place it in the freezer and make sure that the jar’s top edge is even with the surrounding freezer space. If you’ve chosen to freeze your jam in a metal can, be sure to cover it completely.

STEP 3 Label the contents of the jar

If you’re freezing jam in a plastic or glass container, you can simply label the jar “Jam.” If you’ve frozen jam in metal, be sure to write on the lid or label the contents of the jar.

STEP 4 Check the temperature of the freezer regularly. 

You should check the temperature every few days. If the temperature drops below 40 degrees Fahrenheit, move the jar back into the freezer.

You can also use your oven to help keep the jam frozen. Simply wrap the jar tightly in aluminum foil and bake it at 200 degrees Fahrenheit for about four hours.

STEP 5 Enjoy! 

After six months, you can remove the jar from the freezer and enjoy your homemade jam.

How to Defrost Frozen Jam?

Jam is one of those things that’s so simple to make that you’d think it would be a no-brainer. But when you’re confronted with a jam that’s frozen solid, you may not even know what to do.


STEP 1 Pour boiling water into a saucepan until it covers the bottom of the pan. Then set the pan on a burner and heat the water until it boils.

STEP 2 Turn the burner off, wait for the water to cool a bit, then add the jam.

If your jam has frozen in a bowl, it might be hard to get the lid off. If you can’t get the lid off, just put a towel over the top of the bowl and microwave the jam for a few seconds to warm it up.

STEP 3 When the jam is lukewarm, pour it into the jar.

What is the best type of jam to eat?

If you want to avoid getting sick after eating a lot of jam, choose one that contains pectin.

This will help to keep the bacteria away. Some other jams include raspberry preserves, apricot preserves, strawberry preserves, peach preserves, blackberry preserves, apple butter, and grape jelly.
