Mary Berry Strawberry Jam

Mary Berry Strawberry Jam

Mary Berry’s strawberry jam is a traditional British preserve made by gently cooking fresh strawberries with sugar and lemon juice until it reaches the setting point. Following the practical, reliable style of Mary Berry, the focus is on preserving fruit flavour, achieving a clear set, and avoiding overcooking.

Ingredients

  • Fresh strawberries – 1 kg, hulled

  • Jam sugar – 1 kg

  • Lemon juice – 2 tablespoons

Instructions

  • Prepare the fruit – Cut large strawberries in half and place in the pan.

  • Soften gently – Add lemon juice and heat slowly until strawberries release their juices.

  • Mash lightly – Break down the fruit for an even texture.

  • Add sugar – Stir in jam sugar and heat gently until fully dissolved.

  • Boil to set – Increase heat and boil rapidly for a few minutes.

  • Test for setting – Drop a little jam onto a cold saucer and push with your finger; it should wrinkle.

  • Skim if needed – Remove any foam from the surface.

  • Jar the jam – Pour into warm sterilised jars and seal immediately.
