Eat local: Blueberry Refrigerator Jam

Here is a recipe for blueberry refrigerator jam that does not require any additional pectin (which is hard to find in some regions right now). In addition to making a fantastic spread for snacks and sandwiches, it also is an amazing topper for ice cream or sorbet.


  • 1 pound fresh blueberries
  • 3/4 cup granulated sugar
  • 2 Tablespoon fresh squeezed lime juice
  • 1 teaspoon finely grated lime zest


  1. Combine blueberries, sugar, lime juice, and lime zest in a medium saucepot. Bring mixture to boil over medium-high heat. Once mixture has come to a boil, reduce heat to medium.
  2. Place a couple metal spoons in the freezer while you cook the jam. Let the jam cook for 15-25 minutes until the blueberries have broken down and the mixture has thickened.
  3. To test for doneness, dip frozen spoon into hot jam mixture. The jam should fall off the spoon slowly in one thickened mass. If it does not, continue to heat the jam for another 5 minutes before testing again.
  4. Transfer cooked jam into glass jars with tight fitting lids. Let the jam cool uncovered to room temperature. Then cover and keep jam in refrigerator for up to two weeks.

    Nice recipe, but it takes as much time to make as regular jam, which keeps much longer. There are various low-sugar recipes available, such as those from Pomana Pectin, which can be ordered on line if it is not available locally.

    Nice recipe for “self sufficiency” folks, but definitely not for those of us with diabetes, Type 2 or the real deal.

    I tried it, wasn’t very good, too bland. I threw it out.
