Grease a springform pan (26 cm Ø) and sprinkle with semolina. Melt the fat, let it cool down a little. Mix eggs, 125 g sugar and salt with the whisk of the hand mixer until creamy. Stir in curd and sauce powder. Finally fold in the fat. Fill the quark mixture into the mould.
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 30-40 minutes. Leave to cool for approx. 10 minutes with the oven door open. Let cool down on a cake rack. Spread the berry mixture on kitchen paper and allow to defrost. Soak gelatine in cold water. Mix mascarpone, yoghurt and 50 g sugar. Squeeze the gelatine, dissolve it, stir some cream into the gelatine. Then stir everything into the cream. Remove the cake from the mould. Spread the mascarpone cream over it. Add the fruit and chill for about 2 hours. Warm up the jam slightly in a pot and pass through a sieve.
