Mix flour, 3 tablespoons of sugar, 1 packet of vanillin sugar and salt in a bowl. Add the egg yolks and butter in small pieces and knead first with the dough hook of the hand mixer, then with your hands to a smooth dough. Grease 6 tartlet cups with lift-off base (approx. 12 cm Ø) and dust with flour. Roll out the dough thinly on a lightly floured work surface and cut out 4 circles (each approx. 16 cm Ø). Line 4 moulds with the dough and press the edges well down. Cut off any excess dough.
Prick the cake several times with a fork. Knead the remaining dough again and roll out. Cut out 2 more circles, place them in the remaining moulds and prick them as well. Freeze the ramekins for approx. 2 hours, remove them and bake immediately in a preheated oven (electric range: 225 °C/ convection oven: 200 °C/ gas: level 4) for approx. 15 minutes. Remove the tartlets and let them cool down. Mix mascarpone, 2 tablespoons of sugar, 1 packet of vanillin sugar and sour cream. Finely chop 75 g chocolate. Whip cream until stiff and fold into the cream with the chocolate. Coarsely chop 75 g chocolate and melt with the coconut oil over a warm water bath. Clean and wash the strawberries and dab them dry. Remove the tartelettes from the moulds.
