2 Rinse the raisins and soak in rum. Stir together the quark and eggs in a mixing bowl. Add the sugar, vanilla sugar, pudding mix, baking powder, semolina flour, chopped candied orange peel and raisins. Spread the mixture on a parchment-lined baking pan and bake for about 60 minutes. If the cake begins to darken, cover with aluminum foil. Remove and let cool slightly, remove from the tin and dust with powdered sugar. Serve sliced into squares.
