Cream 250 g butter, 250 g sugar and vanillin sugar. Stir in 4 eggs individually. Mix flour and baking powder. Alternating with the milk, also stir in briefly. Pour the dough into a greased springform pan (26 cm Ø) sprinkled with breadcrumbs. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 30 minutes.
In the meantime separate 3 eggs. Beat the egg white, 1 pinch of salt and 1/2 teaspoon lemon juice until stiff. Add 150 g sugar. Continue beating until the sugar has dissolved. Take the springform pan out of the oven. Spread the beaten egg whites loosely over the surface. Leave an approx. 2 cm wide rim. Bake for another 30 minutes.

Stir the starch and a little water until smooth, stir into the juice, bring to the boil again. Whisk the egg yolks and stir in.
