Sieve the starch, 200 g flour, baking powder and 120 g icing sugar into a bowl. Add butter, 1 egg, egg yolk and 1 pinch of salt and knead everything quickly to a smooth dough. Grease a springform pan (28 cm Ø). Roll out the dough on a floured work surface to a circle (36 cm Ø) and place it in the form, forming a rim. Prick the dough base several times with a fork. Put the base in a cool place for about 1/2 hour.
Wash the limes hot, dry and finely grate the peel. Sift 80 g flour. Separate 4 eggs. Mix 60 g sugar, sifted flour, vanillin sugar and milk. Stir in egg yolks, lime zest and quark. Beat the egg whites until stiff, gradually adding 60 g sugar and 1 pinch of salt. Whip cream until stiff. Fold the beaten egg whites and cream into the quark mixture one after the other. Spread the cream on the pastry base and smooth it down. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 45 minutes. Let the finished cheesecake cool in the tin. Carefully remove the edge of the springform pan.
