Peel, quarter and core all but one apple. Cut the apple quarters into pieces, sprinkle with 3 tbsp. lemon juice. Boil 400 ml apple juice. Stir pudding powder, 50 g sugar and 50 ml apple juice until smooth. Bind the apple juice with it. Stir in apple pieces, let simmer for about 2 minutes. Remove from the heat and let it cool down. Pre-cook the lasagne sheets in boiling water for 5-7 minutes, remove and drain
For the sauce, mix sauce powder and 40 g sugar. Stir with approx. 6 tbsp. cold milk until smooth. Bring 240 ml of milk to the boil in a saucepan and remove from the heat. Stir in the mixed powder with a whisk. Bring the sauce to the boil while stirring, remove from the stove. Stir in mascarpone and let it cool down
Wash the rest of the apple, grate dry, halve and remove the core. Cut apple into thin slices, sprinkle with 1 tbsp. lemon juice. Spread a thin layer of mascarpone sauce (2-3 tablespoons) in a greased casserole dish (1.5 litres capacity). Cover with 3 lasagne plates. First spread half of the apple compote on it, then half of the cranberries. Cover again with 3 lasagne plates. Pour the rest of the apple compote and cranberries on top. Finish with 3 lasagne sheets and spread thinly with 150 ml mascarpone sauce. Spread apple slices on top. Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: see manufacturer) for about 20 minutes. Take out and sprinkle with sugar-cinnamon mixture. Add the remaining mascarpone sauce
