Roughly chop the chocolate. Place in a metal bowl and melt on a hot water bath at low heat. Remove from the hotplate and let it cool down a little (lukewarm). Separate the eggs. Beat the egg yolks and sugar until creamy white in a tall beaker with the whisks of the hand mixer. Whip the cream until stiff and allow the vanillin sugar to trickle in.
Beat the egg white until stiff. Let the egg yolk cream run into the lukewarm chocolate and stir in. Add liqueur and cinnamon and stir in. First fold in cream and then beaten egg white in portions. Pour into a dessert bowl and serve decorated with chocolate rolls, mint and orange wedge
