Freezing jam is a great way to preserve summer flavours and enjoy them all year long. Follow the simple instructions below for prime results.
Freezing jam is as simple as packaging it and finding a spot in your freezer. It's best to freeze full jars of jam, so be sure to fill the container to about 1/2 inch from the top. This will decrease the amount of air in the jars and help prevent against freezer burn.
Considerations for glass
Since jam doesn't dramatically expand as it freezes, it's safe to use sturdy, thick-sided glass jars. Plastic containers also work well.
To thaw your frozen jam, place the container in the refrigerator until it thaws. You can also put the jar in warm water (not hot) and thaw it gently in the sink.
Be sure to fill the containers up to 1/2 inch below the top of the container and no more. Overfilling can cause the container to burst due to air expansion during freezing.
Frozen jam should be consumed within six months to one year after freezing. After a year, flavours will start to lose their character and intensity. The consistency of thawed jam may be softer and more watery than prior to freezing. Do not refreeze after thawing.
