Mix 4 tablespoons of milk and cornstarch. Bring the remaining milk and vanilla pulp to the boil. Stir sugar, except for 1 tablespoon, and starch into the boiling milk and bring to the boil again while stirring. Remove from heat. Whisk the egg yolks with a little hot vanilla sauce, then return to the sauce while stirring. Let the sauce cool down. Peel apples and cut out the core.
Chop the walnuts. Mix nuts, sultanas, remaining sugar, cinnamon and fat and fill into the apples. Then place them in an ovenproof dish and pour the wine over them. Cook in the preheated oven (electric cooker: 175 °C/ gas: level 2) for about 30 minutes. In between, cover with wine. Serve with vanilla sauce
