Roast ground almonds in a pan without fat until golden brown. Bring milk, sugar, vanillin sugar and salt to the boil. Set aside 1 tablespoon of almonds. Stir the remaining almonds and semolina into the milk and bring to the boil briefly. Remove from heat and let the semolina swell for about 5 minutes.
Separate the egg. Stir the egg yolk into the hot semolina. Beat the egg white until stiff and fold in. Pour into 4 suitable dessert glasses and let cool. For the sauce chop chocolate finely. Heat the cream and melt the chocolate in it. Peel the mandarins so that the white skin is removed. Cut the fruit into slices and arrange on the semolina. Serve decorated with remaining almonds, mint leaves and roasted almond halves.
