Tips & Tricks

  • Use fully ripe blackberries for the best natural sweetness and color.
  • Simmer gently and stir often to prevent sticking or scorching.
  • Add a splash of lemon juice—it helps the jam set and balances the flavor.
  • Prefer a smoother texture? Gently mash or blend the berries before cooking, and strain for a seedless version.
  • Store in sterilized jars and refrigerate, or process in a water bath for longer shelf life.
  • Spread over warm toast, scones, or crumpets for a cozy breakfast.
  • Swirl into yogurt, oatmeal, or cottage cheese for a naturally fruity touch.
  • Use as a filling in jam bars, cupcakes, or layered cakes.
