Refrigerator Jam

Many jam and jelly recipes call for pectin to thicken the fruit mixture. This recipe relies on the natural pectin released by the berries as they cook. Once the jam is cooked, it can be eaten right away, warm on a slice of buttered toast. Rather than processed in a water bath for cupboard storage, this jam is stored in the refrigerator. The hardest part of making this jam is keeping the kids from eating the berries before you get them home from the market. They can each have fun taking a turn at stirring the fruit and sugar before cooking. They can also pick over and rinse the berries, measure the fruit and sugar, and squeeze and measure the lemon juice. With so many berry varieties to choose from, your kids will have fun mixing and matching their favorites.–Leslie Jonath and Ethel Brennan

Refrigerator Jam Recipe

  • 2 H
  • Makes 2 pint jars or 4 half-pint jars

Ingredients

  • 2 1/2 pounds mixed berries, such as raspberries, boysenberries, and/or blackberries (about 7 cups, but go by weight as types of berries vary in cup amount)
  • 1 1/2 pounds (about 2 1/4 cups) granulated sugar, or less to taste if you’re not a sweet tooth
  • 1 tablespoon freshly squeezed lemon juice

Directions

  • 1. Thoroughly wash two pint or four half-pint canning jars and their lids and screw bands. Place the jars, lids, and screw bands in a large pot and add water to cover. Bring to a boil and continue to boil for 15 minutes to sterilize them. Turn off the heat and leave the jars, lids, and bands in the hot water until ready to use. Place a small plate in the freezer for testing the jam.
  • 2. Pick through the berries, discarding any soft or rotten ones. Gently rinse the berries and place them in a large, heavy nonreactive saucepan. Add the sugar and stir to combine. Bring the mixture to a boil over medium heat, stirring constantly until the sugar dissolves. Stir in the lemon juice. Reduce the heat and simmer the berry mixture, stirring often with a wooden spoon, until the jam thickens to a viscous consistency, 1 to 1 1/2 hours. As the jam cooks, use a large spoon to skim any foam from the surface. After the jam has cooked for an hour, test it to see if the jam has reached the jell point by removing the plate from the freezer, placing 1 teaspoon jam on the plate, and tipping the plate slightly. If the jam doesn’t spread, it’s ready. You can also test the jam for readiness with a candy thermometer, which should register 220ºF (104ºC) when the jam reaches the jell point. [Editor’s Note: “Jell” point or “gel” point? We rather have an affinity for “jell,” thinking perhaps it’s an old-fashioned term for the proper consistency. As such, we rather like to use it, even though it’s not in common parlance.]
  • 3. Lift the jars, lids, and screw bands from the water, using tongs if the water is still hot, and thoroughly dry them. Carefully ladle the hot jam into the sterilized jars, leaving a 1/2-inch space between the jam and the top of the jar. Wipe each jar rim clean with a damp towel, then top with a lid and seal tightly with a screw band. Let the jars cool overnight at room temperature. Label the jars with the recipe name and date. You can store them in the refrigerator, unopened, for up to 3 months. Once opened, use within a week or so.
