Wash and clean the gooseberries. Mix with 100 g sugar (for very sour berries use 1-2 tablespoons more sugar). Leave to infuse for about 10 minutes. Melt the butter and let it cool down a bit. Mix ground almonds, 100 g sugar, salt, lemon zest, vanillin sugar and flour. Add butter and work into crumbles with the dough hooks of the hand mixer. Cover and chill for 15 minutes.
Brush small ramekins with butter, add gooseberries. Spread crumbles on top. Bake in the preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: level 2) for 25-30 minutes. Let cool down a little. Coarsely chop the almonds. Dust crumble with icing sugar and sprinkle chopped almonds over it. Serve with crème fraîche, sour cream or a scoop of vanilla ice cream
