Mix quark, crème fraîche, 250 g sugar, lemon juice, eggs, pudding powder and semolina. Pour the quark mixture into a greased and floured springform pan (26 cm Ø) and smooth it down. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: not suitable/ gas: level 2) for 50-60 minutes. If necessary, cover after 40 minutes of baking time. Remove the cake from the oven, remove from the edge of the springform pan and let it cool on a cake rack for 2 hours. After about 1 1/2 hours, drain the mandarin oranges and pineapple pieces, collecting the juice. Clean, wash, halve and seed the grapes.
Mix the fruit and put it on the cake. Fill up the collected fruit juice with water to 250 ml. Mix cake glaze, 2 tablespoons sugar and juice. Bring to the boil and drizzle over the fruit. Let the cake glaze dry for about 30 minutes. Whipped cream tastes good with it
waiting time approx. 1 1/2 hours
