Defrost the strawberries. Soak gelatine in cold water. Beat the yoghurt, crème fraîche, lemon juice and sugar with the whisk of the hand mixer. Squeeze out the gelatine and dissolve in lukewarm water. Stir into the prepared cream and chill. Whip cream and vanilla sugar until stiff. As soon as the cream begins to firm up, fold in the cream.
Pour into a bowl and allow to set in the fridge. Refine and puree the strawberries that have meanwhile defrosted with Campari. Use 2 tablespoons or an oval ice-cream scoop to cut the cream into cams and arrange on dessert plates. Spread the strawberry sauce around the dessert plates as a blob and use a wooden skewer to pull them apart into stars. Decorate with fresh strawberries, carambola slices and lemon balm. Sprinkle with pistachios
