Sprinkle raspberries with 50 g sugar and drizzle with orange liqueur. Defrost at room temperature for about 2 hours. Separate the eggs. Beat the egg whites with the whisks of the hand mixer until stiff, sprinkle 30 g sugar and vanilla sugar. Stir in the egg yolks one after the other.
Sift the flour and starch onto the egg foam mixture and fold in carefully. Draw 6 circles (8 cm Ø) on 2 baking trays lined with baking paper and spread the dough in the circles with a tablespoon. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 8-10 minutes. Turn the omelettes over onto 2 tea towels and let them cool down. Carefully remove from paper. Stir mascarpone, quark, 50 g sugar, lemon juice and zest until smooth. Pour cream into a piping bag with a medium star-shaped spout. Spray cream onto one half of the omelettes, fold the other half over. Pipe the rest of the cream as a rosette onto 6 dessert plates. Place 2 omelettes on each plate.
