Mix 4 tablespoons cherry juice and starch until smooth. Boil up the rest of the juice and 2 tbsp. sugar. Stir in starch and bring to the boil again. Add berries, fold in and put into a bowl. Let cool down
Whip the cream until stiff, allowing the cream firmer to trickle in. Mix soured milk, lemon juice and 2 tbsp. sugar. Carefully fold in the cream
Layer the soured milk cream and the groats in tall glasses. Mix the layers lightly with a long spoon, so that streaks appear. Sprinkle dessert with chopped pistachios. Keep cool until serving
You can replace soured milk with whole milk yoghurt
Instead of frozen berries, blueberries from a glass jar or canned raspberries also taste good: they boil up in their own juice without adding sugar, bind
