Separate eggs. Beat the egg whites and 3 tablespoons of cold water until stiff, adding 100 g of sugar. Stir in egg yolks. Mix flour, starch and baking powder, sieve over the mixture and fold in. Pour the mixture into a piping bag with a perforated spout.
Spray 6 spiral circles (approx. 10 cm Ø) each on 2 baking trays lined with baking paper. Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 8-10 minutes. Remove the sponge cake and let it cool down. Remove the bases from the baking paper. Sprinkle some almond liqueur on 6 cake layers. Roughly chop the chocolate and melt in a bowl over a warm water bath. Put the chocolate in a small freezer bag and cut off a small corner. Decorate sponge cake bases spirally with chocolate. Sort the raspberries. Mix quark, vanillin sugar, cream setting agent and 2 tablespoons of sugar.
