Drain the plums and collect the juice. Stir 4 tablespoons of juice and starch until smooth. Boil up the rest of the juice, vanilla sugar and cinnamon. Stir the starch into the boiling juice and simmer for 2-3 minutes. Fold in plums and wine. Let the compote cool down.
Whip the cream until semi-stiff, pour in the sauce powder. Stir in yoghurt. Arrange plum compote in small bowls and add a blob of yoghurt cream to each. Sprinkle with almonds. Decorate with mint
