Drain the peaches. Sieve the flour and icing sugar into a bowl. Sprinkle lemon peel over it. Add fat in pieces, egg yolk and 4 tablespoons of water. Knead everything with your hands to a smooth dough.
Wrap in cling film and leave to rest in the fridge. Separate the eggs for the filling. Mix quark, mascarpone, sugar, vanillin sugar, pudding powder, egg yolk and cream. Grease a springform pan (26 cm Ø). Roll out the dough between 2 layers of cling film to a circle (approx. 30 cm Ø). Line the bottom and the edge of the form with dough and press the edge slightly. Prick the base of the dough several times with a fork. Sprinkle breadcrumbs on the base. Dab the peaches dry with kitchen paper and lay them on the cake base. Beat the egg whites until stiff, carefully fold them into the quark mixture in portions and spread evenly over the peaches.
