Peel the apples and cut into small pieces. Bring to the boil with apple juice and sugar and cook a little. Mix the pudding powder with a little water and stir into the apples. Let it boil briefly once. Mix in the frozen raspberries. Thanks to the frozen berries, the grits cool down quickly and the berries do not disintegrate.
Chill until the grits have set. Cold milk (for household use) or vanilla sauce (for guests) also tastes good.
