Sort the raspberries and carefully rinse with cold water if necessary. Wash, drain and clean the currants and strawberries
Mix the starch and 6 tbsp. currant juice until smooth. Boil up the rest of the juice, lemon peel and vanilla sugar. Stir in the starch, bring to the boil and simmer for another 3 minutes. Add fruit. Season the groats with sugar if necessary. Leave to cool slightly and remove lemon peel
Arrange the groats in dessert bowls or a bowl and let them cool completely. Shape the ice cream into balls with an ice cream scoop or use a moistened tablespoon to cut into cams and arrange on the groats. Decorate with mint leaves if desired
