Mixed Berry Freezer Jam- Homemade jam that requires zero canning experience and tastes a million times better than anything you buy at the store. 

Mixed Berry Freezer Jam

Way back in the day, when I received this recipe, it wasn't called "freezer jam".  It was just homemade jam.   I loved it because it didn't involve the whole "canning" protocol.  


I made it, put it in mason jars and put it in the fridge.  No boiling, sealing and worrying about air getting into the jars.  One jar was in the fridge, the rest were stored in the freezer.  So easy!

Ingredients Needed

  • Cornstarch

Should I Use Fresh or Frozen?

  • Use whatever you have in your kitchen. They will both work.  The only difference is that your frozen berries will take a little longer to break down.  Be sure if you are using fresh, that your berries are clean, sliced and have the stems removed.
  • You can use a combination of mixed berries (strawberries/blueberries/raspberries/blackberries) or simply use your favorite berry.  You will need 2 cups.

What does the Cornstarch and Lemon Do?

  • I don't use pectin.  You can, if you wish.  However, I always have cornstarch in my pantry, so, it's just easier.  The cornstarch (and pectin) act as a thickening agent.
  • Lemon juice will help in preventing the berries from turning brown.


Storage

  • Filling Jars:  When you are filling your jars, leave about a 1/2 inch to an inch of space at the top of the jar for expansion space. 
  • Keep any leftover jam in a tightly sealed jar or container.  If you are storing in the refrigerator, it is best to eat the jam within two to three weeks.  If you are freezing your jam, store it in tightly sealed, freezer safe jars.  They will stay good in your freezer for up to a year.
