Soak gelatine in cold water. Separate eggs. Whip egg yolks, sugar and vanillin sugar until creamy white. Add orange juice, wine and liqueur and stir well. Squeeze out the gelatine and melt in a small pot at low heat.
Carefully stir the gelatine drop by drop into the egg-wine mixture and chill (until it draws streets). In the meantime, whisk the cream with the whisk of the hand mixer until stiff. Beat the egg whites until stiff.
Carefully fold cream and egg white into the gelatinizing mass in portions. Pour into a dessert bowl and chill for 4-5 hours. Peel off the chocolate with a peeler. Sprinkle the dessert with chocolate rolls and serve decorated with orange peel, orange slices and lemon balm.
