Rub the peel of an orange with a grater. Peel and fillet all oranges. Reduce the orange juice to a quarter of a liter.
Soak the gelatine leaves in cold water, squeeze out and dissolve in the boiled down, slightly cooled orange juice.
Mix the quark, sugar and orange juice / gelatin mix to a cream. Then stir in the grated orange peel.
Whip the cream with a little sugar and fold into the cream. Put the mousse in the refrigerator for at least 12 hours.
To serve, shape the orange mousse into dumplings with a wet spoon and garnish with orange fillets.
You can also cook a warm sauce from a little orange juice with a little sugar and a dash of orange liqueur, into which a few cold butter flakes are stirred in at the end. Drizzle the orange sauce around the mousse socks with some space and serve.
The sauce is not a must, it also tastes great WITHOUT.
