Peel the mango. Remove the pulp from the stone and cut into small cubes. Wash and sort the blueberries.
Put the blueberries and the mango cubes in a bowl. Mix the yoghurt with crème fraîche until smooth, season with sugar and cinnamon to taste and add a pinch of vanilla powder.
Grind about 1 teaspoon of dried peppermint in a mortar and add to the cream. More or less peppermint can be used. Mix the fruits and the cream and distribute in dessert glasses.
If you put the fruit salad in a cool place, the peppermint unfolds its full freshness.
