Preparing the apple filling
Mix the raisins with the rum. Let them steep. Preheat the baking oven to 180°C. Melt the butter in a pan and roast the breadcrumbs. Wash the apples and peel them. Cut them into halves, remove the core casing and cut the apples into small pieces. Sprinkle them with the lemon juice, add the crumbs, the gelling sugar, the vanilla sugar, the cinnamon and the prepared raisins and mix thoroughly with the cooking spoon.
