Separate eggs. Beat the egg whites, salt and 3 tablespoons of lukewarm water until stiff. Add 75 g sugar and continue beating. Stir in the whole egg yolk and lemon peel briefly. Mix flour and starch, sieve onto the egg mixture and fold in.
Draw a circle of about 24 cm on a baking tray lined with baking paper. Spread 1/3 of the dough on it. Sprinkle with 1/3 of the flaked almonds. Bake in a preheated oven (electric: 200°C/ gas: level 3) for 8-10 minutes.
Let it cool down. Then bake two more bases as before. Soak the gelatine in cold water. Wash and clean the strawberries. Place one pastry base on a cake plate. Place the strawberries close together.
Whip cream, remaining sugar and vanilla sugar until stiff. Squeeze the gelatine, dissolve and stir into the cream. Spread half of the vanilla cream over the strawberries. Place the second cake layer on top. Spread with the remaining cream and cover the last cake layer.
Put the cake in a cool place for about 1 hour. Serve dusted with icing sugar. Makes about 12 pieces.
