Quick Berry Jam

A no-pectin preserve made for a homegrown berry glut
DIFFICULTY Easy
COURSE Condiment
CUISINE British-inspired
Use properly sterilised jars and seal while the jam is still hot - this creates a vacuum seal as it cools, which is what makes the jam shelf-stable. Jars that don't seal properly should be refrigerated and used within a few weeks.

01Ingredients

  • 1000g berries (raspberries, strawberries, or a mix), hulled if needed
  • 800g white sugar
  • 2 tbsp lemon juice

02Method

  1. Place berries, sugar, and lemon juice in a large, heavy-based pot. Let sit for 10 minutes to release some juice.
  2. Bring to a boil over medium-high heat, stirring to dissolve the sugar.
  3. Boil rapidly for 15-20 minutes, stirring occasionally, until it reaches setting point (a small amount dropped on a cold plate wrinkles when pushed).
  4. Skim off any foam from the surface.
  5. Pour hot jam into sterilised jars and seal immediately.

03Notes & substitutions

  • A mix of berries gives a rounder flavour than one type alone.
  • Reduce the sugar slightly if the berries are very sweet already, though this may extend the boil time needed to set.
  • Add a few whole berries near the end for texture, rather than boiling them all to a smooth consistency.
  • Vegetarian and vegan as written.

04Common mistakes

  • Not boiling long enough — jam needs a rapid boil to reach setting point; a gentle simmer will never set properly, however long you leave it.
  • Skipping the setting point test — jam that looks ready in the pot can still be runny once cooled; always test on a cold plate before jarring.
  • Using unsterilised jars — this affects both shelf life and safety; always sterilise jars properly first.
