Drain the cherries and let them drain well. For the sponge mixture, mix fat, 150 g sugar, "fine lemon peel" and salt until creamy. Stir in four eggs bit by bit. Mix flour and baking powder and stir briefly into the fat egg mixture. Stir in milk. Put the dough on a greased baking tray (32x37 cm) and smooth it down.
Pre-bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for 10 minutes. In the meantime, mix sour cream, sauce powder, remaining sugar and two eggs. Spread the cherries on the pre-baked base. Pour over the sour cream and bake for another 20-25 minutes. Let it cool down and dust with icing sugar. Makes 20 pieces
