Separate eggs, beat egg whites until stiff. Add 50 g sugar, vanillin sugar and salt. Fold in egg yolks, mix flour and baking powder, sieve over the egg mixture and fold in. Line a baking tray with baking paper and draw 4 circles (each 13 cm Ø) on it. Spread half of the dough into the circles and spread.
Bake the omelettes in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 10-12 minutes. Turn the omelettes onto a tea towel sprinkled with sugar and cover with another, moistened tea towel. Do the same with the remaining dough. Whip cream, 50 g sugar, lemon juice and zest until stiff. Pour cream into a piping bag with a large star-shaped spout. Spray one half of the omelet with the star spout and fold over. Spray a cream tuff on each omelette. Cut the peel into fine strips. Decorate omelettes with lemon balm and lemon peel.
