How to Make Freezer Jam | Raspberry Freezer Jam
Melissa Griffiths
Learn all the tips and tricks for how to make freezer jam that is perfect every time. All you need is a bowl, a whisk, and some time! No cooking is required.
Crush berries to desired consistency - do not strain (see note).
Mix with lemon juice.
Gradually whisk in pectin.
Set two timers simultaneously - one for 30 minutes and one for 5 minutes. Mix every 5 minutes for 30 minutes. This ensures that the pectin is completely mixed in.
After the 30 minutes, whisk in sugar.
Whisk for 2-3 minutes until the sugar is completely dissolved.
Transfer to CLEAN jars.
Let set for 24 hours.
Freeze or refrigerate after jam as set for 24 hours.
Notes
The amount of berries you use can vary slightly, within half of a cup. More variation than that will lead to problems with your jam setting up.
Fruit (and vegetables) naturally contain pectin, and different kinds of fruit contain differing amounts of pectin. Softer fruit has less pectin, and more firm fruit has more pectin. The way freezer jam is set up is by adding more pectin. The most common reason for freezer jam to not set up is a problem with the pectin to fruit ratio.
Let the jam cool completely before putting it in the freezer. This prevents condensation from forming inside the containers, which can affect the texture and quality of your jam.
Freezer jam can be stored in the freezer for up to one year, but it’s best consumed within 6-8 months for optimal flavor.
