Grease a tart mould with a lifting base (26 cm Ø) well and dust with flour. For the shortcrust 175 g flour, 75 g sugar, 1 packet of vanilla sugar, 1 pinch of salt, 75 g butter in pieces and 4-6 tbsp ice-cold water, first with the dough hooks of the mixer, then quickly knead into a smooth dough with your hands.
Roll out the dough on a little flour until round (approx. 30 cm Ø). Put it into the tart tin, press the rim. Prick the base several times with a fork. Cover and chill for about 30 minutes.
For the topping, wash the gooseberries, drain well in a sieve and clean. Mix the crème fraîche, 75-100 g sugar, 1 packet vanilla sugar, sauce powder and eggs with the whisks of the mixer until smooth.
Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3). Sprinkle the base evenly with almonds. Spread gooseberries on top. Pour the icing over it. Bake in the hot oven on the lowest shelf for 45-55 minutes.
Remove from the oven and let it cool down. Whipped cream tastes good with it.
