Knead flour, 35 g sugar, 1 pinch of salt, 1 egg and 100 g butter in flakes to a smooth dough. Cover and chill for about 30 minutes. Grease the cake pan (12 cm Ø) with a removable base. Roll out the dough thinly in portions on a floured work surface. Cut out circles (approx. 14 cm Ø) and line the moulds with them. Cut off protruding edges.
Place baking paper on the dough, cover with legumes. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 15 minutes. Carefully remove the baking parchment with the pulses. Bake the tartlets for another 8-10 minutes, let them cool down. For the cream, squeeze out grapefruit, measure 200 ml juice. Pour the starch into an ovenproof bowl and stir until smooth with the juice. Separate 1 egg. Set aside the egg white. Stir 5 egg yolks and 150 g sugar into the juice mixture. Add 75 g butter in flakes. Heat everything over a hot water bath while stirring until the cream thickens.
