Peel oranges so that the white skin is completely removed. Cut oranges into slices, mix with liqueur and marinate for about 30 minutes
Mix espresso and 2 tablespoons of sugar and let it cool down. Finely chop the chocolate. Mix mascarpone, quark, chocolate and 50 g sugar
Let oranges drip off a little. Line the bottom of a rectangular form (approx. 15 x 20 cm) with half of the sponge fingers, sprinkle half of the espresso and spread a thin layer of cream on top. Cover with half of the orange slices, spread another thin layer of cream and spread the rest of the lady fingers on top. Drizzle with espresso and repeat the process with a little cream and the remaining oranges. Loosely wave the remaining cream on top, chill for approx. 3 hours.
