I made this using buttermilk and bananas, 'cause we had a bunch that needed eating, but you could also use frozen berries. And, if you prefer a frozen yoghurt, I don't see why you couldn't use plain yoghurt in place of the buttermilk. The bananas do give it a thick, creamy texture though, that you may not get from berries, but hey - if it's more like a berry sorbet, so much the better!!
chopped bananas (about 6)
600 ml buttermilk
- Chop bananas and place in the freezer.
- When frozen blend in food processor with buttermilk until smooth and creamy.
- Scoop into freezer-proof container (with a lid) and freeze until ready to use.
