Jam Ingredients

  • 4 cups fresh blackberries
  • 2 cups granulated sugar
  • 2 tablespoons fresh lemon juice
  • ¼ teaspoon salt

Instructions

  1. Combine Ingredients: In a large saucepan, combine the fresh blackberries and granulated sugar. Let the mixture sit for 20 to 30 minutes so the berries begin to release their juices, which helps with the cooking process.
  2. Heat Mixture: Place the saucepan over medium heat and bring the berry mixture to a gentle boil. Stir occasionally and mash the berries as they soften to help break them down.
  3. Cook Down: Continue cooking, stirring frequently, until the berries completely break down and the mixture thickens to a jam-like consistency.
  4. Add Lemon Juice and Salt: Stir in the fresh lemon juice and salt. Allow the jam to simmer for a few more minutes, which enhances the flavor and ensures proper thickening.
  5. Strain Seeds (Optional): Remove the pan from the heat and, if you prefer a smoother texture, strain the jam through a fine-mesh sieve to remove the seeds.
  6. Cool and Store: Let the jam cool slightly, then transfer it to clean jars. Allow it to cool completely before sealing and storing in the refrigerator for best freshness.

Notes

  • Use fresh, ripe blackberries for the best flavor and natural sweetness.
  • Adjust sugar quantity depending on your sweetness preference or berry tartness.
  • If you want a seedless jam, do not skip the straining step.
  • The jam will thicken further as it cools, so remove it from heat once it reaches a slightly thinner consistency than desired.
  • Store sealed jars in the refrigerator and consume within 2-3 weeks for optimal freshness.
