For the compote, wash apples, quarter them and cut out the core. Cut the fruit flesh into slices, sprinkle with lemon juice and stew with cinnamon stick and cider for about 15 minutes.
Season to taste with about 3 tablespoons of sugar. In the meantime, stir 2 tablespoons of milk, remaining sugar and sauce powder for the noodles until smooth. Bring the remaining milk and vanilla pulp to the boil briefly. Add the noodles and cook for about 8 minutes.
Carefully stir in the sauce powder. Chop the walnut kernels. Serve pasta and apple compote garnished with walnuts and lemon balm.
