Description

Blackberry Freezer Jam is a no-cook, vibrant fruit spread that captures the fresh, juicy taste of ripe blackberries in a simple, freezer-friendly recipe. It’s quick to make and perfect for spreading on toast, stirring into yogurt, or topping desserts.


Ingredients

  • 3 cups fresh blackberries, washed and mashed
  • 1 1/2 cups granulated sugar
  • 1 tbsp lemon juice (optional)
  • 1 package (1.59 oz) powdered fruit pectin (for freezer jam)
  • 3/4 cup water

Instructions

  1. Mash blackberries with a fork or potato masher until juicy but still slightly chunky. Measure out 3 cups after mashing.
  2. In a bowl, mix sugar and powdered pectin until well combined.
  3. Add water to the sugar-pectin mix and bring to a boil in a saucepan. Boil for 1 minute, stirring constantly, then remove from heat.
  4. Pour hot pectin mixture into the crushed blackberries and stir for 3–5 minutes until thoroughly blended.
  5. Ladle jam into clean freezer-safe containers, leaving 1/2 inch of space at the top.
  6. Let sit at room temperature for 24 hours to set, then transfer to freezer. Thaw before using and store in the fridge for up to 3 weeks after opening.

Notes

  • Use an immersion blender for a smoother jam texture.
  • Combine with raspberries or blueberries for a mixed berry version.
  • Add lemon zest or vanilla extract for extra flavor.
  • Use low-sugar pectin to reduce sugar if preferred.
  • Always use clean utensils to avoid contamination.
