Separate the eggs for the dough. Beat the egg white with 1 pinch of salt in a large bowl until stiff. Beat the egg yolks, vanilla sugar and 250 g sugar in a second bowl with the whisks of the mixer until creamy.
Stir in almonds, lemon and orange peel. Fold in the egg white.
Grease a springform pan (26 cm Ø) and smooth down the dough. Bake in the preheated oven (electric oven: 175 °C/circulating air: 150 °C/gas: see manufacturer) for about 50 minutes. About 12 minutes before the end of the baking time cover the cake with aluminium foil.
Allow to cool, remove from the mould. Place the cake ring around it.
Stir mascarpone, curd and 50 g sugar until smooth, spread on the cake. Chill for about 30 minutes.
Clean, wash and stone the cherries. Stir 4-5 tablespoons of juice with cornflour until smooth. Boil up the remaining juice with 2 tablespoons of sugar in a pot, stir in the mixed starch. Simmer for about 1 minute while stirring.
Carefully fold in the cherries. While stirring several times, allow to cool for about 5 minutes, then spread on the mascarpone cream. Chill the cake for approx. 1 1⁄2 hours.
