Ingredients Method Notes

Ingredients
  

  • 4 cups fresh blackberries
  • 2 cups granulated sugar
  • 2 tablespoons fresh lemon juice
Optional
  • 1 teaspoon lemon zest
  • ½ teaspoon vanilla extract

Method
 

  1. Rinse the blackberries thoroughly and remove any stems or damaged berries.
  2. Add the blackberries, sugar, and lemon juice to a medium saucepan and stir until the berries are coated.
  3. Cook over medium heat, stirring occasionally, until the sugar dissolves and the berries begin to soften.
  4. Gently mash some of the berries with the back of a spoon if you prefer a smoother jam.
  5. Continue simmering for 20–30 minutes, stirring frequently as the mixture thickens.
  6. To test if the jam is ready, place a small spoonful on a chilled plate. If it wrinkles when pushed gently with your finger, it's done.
  7. Remove from the heat and let the jam cool for about 5 minutes.
  8. Spoon into a clean, sterilized jar and allow it to cool completely before sealing.
  9. Store in the refrigerator and enjoy.

Notes

  • Frozen blackberries work well if fresh aren't available.
  • The jam will continue to thicken as it cools.
  • For a smoother jam, strain out the seeds before the final simmer.
  • Store in an airtight jar in the refrigerator for up to 3 weeks.
