Separate eggs. Beat the egg whites, 3 tablespoons of cold water and salt until stiff with the whisks of the hand mixer. Finally, add 60 g sugar and 1 packet of vanilla sugar. Fold in the egg yolks one after the other. Mix flour and baking powder, sieve onto the egg foam and fold in. Line a baking tray (approx. 34 x 41 cm) with baking paper. Spread the mixture evenly on the baking tray. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 8 minutes.
Lightly moisten a tea towel and sprinkle with sugar. Remove the baking tray from the oven, remove the sponge cake from the edge and fall onto the tea towel. Carefully peel off the baking paper, place the edges of the tea towel over the sponge cake and let it cool down
