Cut the vanilla pod lengthwise. Scratch out the pith. Boil up vanilla pulp, milk, butter, 25 g sugar and salt. Sprinkle in semolina while stirring, remove from heat and let it swell to a thick paste.
Let it cool down a little and stir in the egg yolk. Put some raspberries aside for decoration. Caramelise 5 tablespoons of sugar and 2 tablespoons of water in a pot until golden brown. Add the rest of the frozen raspberries and apple juice, boil off the sugar and simmer covered for about 5 minutes.
Meanwhile boil 1 litre of water with 3 tablespoons of sugar once. Use 2 tablespoons of the semolina mixture to form cams, slide into the water and cook for about 10 minutes. Arrange the raspberry soup and semolina noodles in preheated soup plates.
Dust semolina noodles with cinnamon. Crumble the amaretti. Sprinkle soup with it and decorate with mint. Add Mikado sticks.
