Ingredients

Directions

1. 1

   Separate eggs. Beat the egg whites and 4 tablespoons of water with the whisks of the hand mixer until stiff, adding 100 g sugar. Add egg yolk and stir in. Mix flour and starch, sieve portions onto the egg mixture and carefully fold in. Spread the dough evenly on a baking tray lined with baking paper. Bake in a preheated oven (electric: 200 °C/ gas: level 3) for approx. 12 minutes.

   Place a piece of baking paper (slightly larger than the baking tray) on the work surface and sprinkle evenly with 50 g sugar. Remove the sponge cake from the oven and turn it over onto the baking paper. Remove the baking paper and cover with a damp tea towel. Let it cool down. Mix marcarpone, quark, 75 g sugar and cream setting agent with the whisks of the hand mixer. Put 5 tablespoons of cream aside. Peel grapefruits with a knife so that the white skin is also removed. Remove the fillets with a sharp knife. Put 4 fillets aside. Remove the damp tea towel and spread the cream evenly over the biscuit base. Leave the upper edge of the long side free.
