Berry jam in the freezer

Ingredients:

• 0.5 cup granulated sugar
• 2 tbsp soluble pectin (see note)
• A pinch of fine salt
• 2 tbsp. mixed berries, such as blackberries, raspberries, blueberries and peeled strawberries
• 2 tsp freshly squeezed lemon juice

Preparation:

1. In a small bowl, combine the sugar, pectin, and salt, distributing the ingredients evenly. Let sit to prevent the sugar from adding graininess. Mash the berries in a separate large bowl with a fork or potato masher until smooth; add the lemon juice.
2. Add the sugar mixture to the berry mixture and stir until fully incorporated and the sugar is completely dissolved, about 2 minutes (this will also help dissolve the pectin).
3. Transfer to a glass jar or other freezer-safe container and let sit at room temperature for 30 minutes to set. Seal and freeze for up to 1 year.
   
   
   Note
   
   Instant pectin powder is best for making jams in the freezer because it doesn't require cooking or heating to activate. Instant pectin shouldn't be substituted for regular pectin, as the latter requires more sugar and heating. Spread the jam within 1 cm of the rim of the jars, as it will expand during freezing.
