INGREDIENTS

Makes a big tub

1kg freshly gathered blackberries, frozen if out of season
500g golden caster sugar
juice of 1 lemon

Put the blackberries and lemon juice in a food processor and whizz, or in a bowl and puree using a hand blender.

Push through a fine sieve to catch all the pips. Combine with the rolled syrup and put in an ice cream machine to churn or works just as well in a large tuppaware remembering to churn a couple of times having left it for an hour in between. Leave to freeze.

Approximate cost £1.90 assuming you have picked your blackberries!
