Wash the apples, cut off a lid, generously remove the core and hollow out the apples so that an approximately 2 cm wide rim remains.
Crush the hollowed out pulp in a mortar, mix with 1 tablespoon of sugar, cinnamon, raisins, almonds and pistachios and pour into the apples. Spread melted butter on an ovenproof dish, set the apples, sprinkle with sugar, put flakes of butter on top, pour the port wine over it and place in the preheated oven. (220 ° / 20-25 min.)
Arrange the fried apples in dessert bowls.
Make a chocolate sauce from melted chocolate, soft butter and 2-3 tablespoons of apple juice from the baking pan, beat well with a whisk and pour over the apples.
