A simple and forgiving freezer jam recipe using fresh or frozen black raspberries, sugar, and lemon juice, with no pectin required. Perfect for preserving summer flavors with a fresh, fruity punch and homemade texture.

Ingredients

Scale
  • 4 cups (600 grams) black raspberries, fresh or frozen, thawed
  • 3 cups (600 grams) granulated sugar
  • 1/4 cup (60 ml) freshly squeezed lemon juice
  • Optional: 1/8 teaspoon salt

Instructions

  1. Rinse about 4 cups (600 grams) of black raspberries gently under cold water. If using frozen, thaw completely and drain any excess liquid (about 10 minutes).
  2. Place the berries in a large bowl and mash lightly with a potato masher or fork until chunky puree forms, keeping some texture (3-5 minutes).
  3. Stir in 3 cups (600 grams) granulated sugar and 1/4 cup (60 ml) freshly squeezed lemon juice until sugar dissolves slightly (about 2 minutes).
  4. Let the mixture rest at room temperature for 10 minutes to allow sugar to dissolve fully and jam to thicken.
  5. Spoon the jam into clean, freezer-safe jars or containers, leaving about 1/2 inch (1.25 cm) headspace for expansion. Wipe rims clean before sealing.
  6. Let jars cool to room temperature, then place in the freezer. Jam will set in about 24 hours. Thaw in refrigerator or at room temperature before serving.

Notes

Use ripe but firm black raspberries for best texture. Do not over-mash to keep some berry bits. Let the jam rest for 10 minutes after mixing to activate natural pectin. Avoid overheating or cooking the berries to preserve fresh flavor. Stir jam if liquid separates after thawing. Sterilize jars to prevent mold if storing in fridge after thawing. Avoid metal lids for freezing to prevent rust.
