Garden jam

Garden Jam
makes about 3.6kg

450g blackcurrants, stalks removed
450g blackberries
450g raspberries
450g strawberries
1.8kg granulated sugar, warmed

Put the blackcurrants into a large heavy-based pan and add 150ml of water. Bring to the boil and simmer until the berries are almost cooked. Add the rest of the fruit and gently simmer, stirring occasionally, for about 10 minutes, or until the fruit is just turning soft.

Add the warm sugar, and stir over a gentle heat until it has dissolved. Bring to the boil and boil hard until setting point is reached (to test, put a spoonful of jam on to a cold saucer and allow to cool slightly, then push the surface, if a skin has formed and it wrinkles to the touch it is ready).

Pour into warm, sterilized jars. Cover and seal. Store in a cool dark place for up to 6 months.
