Mix flour, 3 tablespoons sugar, vanillin sugar and salt in a bowl. Add the egg yolks and 75 g 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. Chill the ramekins for about 30 minutes. Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: level 4) for 15-20 minutes, remove from oven and allow to cool. Roughly chop the chocolate and melt over a warm water bath. Spread the inside of the tartelettes with the chocolate and leave to dry. Mix ##quark##, 3 tablespoons sugar and advocaat. Whip cream until stiff and fold into the quark. Clean, wash and dry the strawberries. Remove the Tartelettes from the moulds. Pour cream into the moulds.
