Pour the mandarins into a colander and drain well.
Make a shortcrust pastry out of the flour, sugar, butter and water - use it to line a 26-inch springform pan and form a nice high rim (at the end, the rim is knocked a little over the filling and should go to the top).
Mix the quark, cream cheese and yoghurt, stir in grated lemon, sugar, vanilla pudding powder and eggs. Finally fold in the drained mandarin oranges.
Pour the filling into the springform pan and fold the edge inwards.
Bake in a preheated oven at 160 ° for about 50-60 minutes.
Let the cake cool down and serve it cold from the fridge.
