For the base, place flour, salt, 1 packet of vanilla sugar, 75 g sugar, 1 egg and butter in flakes in a mixing bowl. Knead with the dough hook of the hand mixer. Then knead with your hands to a smooth dough
Roll out the dough into a circle (approx. 30 cm in diameter) on a floured work surface. Carefully place the dough into a well greased tart mould (with lift-off base, 26 cm Ø) sprinkled with flour. Press down the edge and base. Prick the base several times with a fork. Chill for about 30 minutes.
In the meantime wash the gooseberries, drain them in a sieve and clean them. For the icing crème fraîche, put 75-100 g sugar, 1 packet of vanillin sugar, sauce powder and 3 eggs into a mixing bowl and mix with the whisks of the hand mixer until smooth
Sprinkle the soil evenly with almonds. Spread gooseberries on top. Pour over the top and bake in the preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) bottom rack for 45-55 minutes. Remove from the oven, place on a cake rack and allow to cool. Serve with whipped cream
