Melt the fat. Put the biscuits in a freezer bag, close it and crumble finely with a rolling pin. Mix with the fat. Place a springform pan rim (24 cm Ø) on a cake plate, press the crumbs evenly into it and chill for about 15 minutes. In the meantime soak the gelatine in cold water. Mix quark, mascarpone, icing sugar, vanillin sugar, lemon juice and zest to a smooth cream. Squeeze the gelatine, dissolve it and stir into the cream.
Spread on the crumb base and chill for approx. 2 hours. In the meantime, wash and drain the currants, except for a few for decoration, from the panicle strips. Wash and clean the strawberries and raspberries. Halve the strawberries if necessary. Warm up the jelly. Spread the fruit on the cake and sprinkle with jelly. Serve decorated with remaining panicles
