Wash 2 apples, grate dry, quarter, core and cut into slices. Put the roulade meat on a kitchen board, salt it and spread with horseradish. Cover with 1 slice of Black Forest Ham and 1 slice of apple slices, roll up and pin with roulade needles. Peel and roughly dice the onions. Heat clarified butter in a casserole and fry the roulades in a frying pan. Finally add onions, fry briefly and season with salt and pepper.
Deglaze with cider and stock, add cinnamon and cloves and bring to the boil. Cover and stew for about 1 hour. In the meantime, spread the potato balls on a baking tray and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 20-24 minutes. Clean the Romanesco, divide into florets, wash and drain. Cook in boiling salted water for 10 minutes. Wash the rest of the apple, grate dry, cut into slices and sprinkle with lemon juice. Heat the fat in a pot and fry the apple slices until soft. Add Romanesco and toss. Keep warm. Remove the finished roulades from the steaming stock. Stir the starch with cold water until smooth. Stir into the stock, bring to the boil briefly and season to taste with salt, pepper and a little sugar.
