Bring 1 litre of milk to the boil, add rice, 2-3 tablespoons of sugar and 1 pinch of salt. Let it swell for about 30 minutes at low heat, stirring occasionally. In the meantime mix 1 tbsp. sugar and sauce powder.
Stir with 3-4 tablespoons of milk (remove from 250 ml milk) until smooth. Bring the rest of the milk to the boil, remove from the heat, stir in the mixed powder with a whisk. Bring to the boil again briefly while stirring.
Let the sauce cool down a little while stirring occasionally. Wash, quarter and core the apples. Cut apples into thin slices. Wash mint and dab dry. Pluck leaves. Arrange rice and apple slices in bowls.
Decorate with mint and pour some vanilla sauce over it. Remaining vanilla sauce extra is enough.
