Berry frozen yogurt:
Place all the ingredients in a jug blender and blend to a smooth puree.
Pour into a plastic container and freeze for a couple of hours.
Simmer in a saucepan until berries have defrosted. Blend to a smooth sauce and then pass through a sieve.
Assorted fresh berries – strawberries, raspberries and blueberries are all good.
Place a scoopful of yogurt into a sundae glass, add a tablespoon of the sauce and some of the mixed berries. Repeat with 2 other scoops and berries and sauce. Serve.
