Melt the butter. Dust with sauce powder. Sweat briefly and add milk while stirring. Stir in vanillin sugar. Bring to the boil. Let cool down briefly and stir in 1 egg yolk.
Finely grate the marzipan. Stir in 2 egg yolks one after the other. Add quark and semolina and mix. Add pistachios, chocolate crumble and candied orange peel to the quark mixture. Pour the mixture into a piping bag and squirt into the cannelloni. Place the cannelloni in 2 rows on top of each other in a greased, ovenproof dish. Pour vanilla sauce over the cannelloni and bake in a preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) for 35 minutes. Meanwhile bring raspberries and sugar to the boil and simmer at low heat for about 5 minutes. Pass the raspberries through a sieve. Stir starch with cold water until smooth. Mix the raspberry puree with the starch and bring to the boil again.
