Drain the cherries. Cream fat, 175 g sugar, vanillin sugar and salt with the whisk of the hand mixer. Stir in the eggs one after the other. Add lemon zest and 1 cup of sour cream and mix. Mix flour and baking powder and stir in.
Grease the fat pan of the oven (32x39 cm). Put the dough on it and smooth it down. Spread the cherries on top and press down a little. Bake in the preheated oven (electric cooker: 175 °C/ gas: level 2) for about 45 minutes. Let it cool down a bit and sprinkle with sugar crystals. Mix the remaining sour cream, sugar and liqueur. Wash the mint, dab dry, pluck leaves from the stalk and, except for a few for decoration, cut into fine strips. Stir into the sour cream. Cut the cake into pieces, arrange on a plate and serve decorated with mint as desired.
