Ingredients

1/2 cup granulated sugar

2 tablespoons instant pectin (see Cook's Note)

Pinch fine salt

2 cups mixed berries, such as blackberries, raspberries, blueberries and stemmed strawberries

2 teaspoons fresh lemon juice

Directions

  1. Stir together the sugar, pectin and salt in a small bowl until combined. Mash the berries in a separate large bowl with a fork or potato masher until evenly and finely crushed; stir in the lemon juice.
  2. Add the sugar mixture to the berry mixture and stir until well combined and the sugar has fully dissolved, about 2 minutes (this will also help the pectin bloom). Ladle into a glass mason jar or other freezer-safe container and set aside at room temperature for 30 minutes to set. Cover and store in the freezer for up to 1 year. 

Cook’s Note

Instant pectin is powdered and best used for freezer jams because it doesn’t require any cooking or heat to activate. Instant pectin should not be used interchangeably with classic pectin, as classic requires more sugar and heat to achieve a nicely set jam. When jarring the jam, leave 1/2 inch of room at the top of the jar for expansion when freezing.
