Soak the sultanas in the schnapps, chop the walnuts a little and add. Add the marzipan in small pieces and mix everything into a mass.
Wash the apples well and cut off a lid at the top. Cut out the core, but the apple should remain closed at the bottom. Drizzle with lemon juice.
Now fill the apples with the marzipan mixture. There should be room for about a good teaspoon of the mixture in each apple. Put a flake of butter on the mixture and put on the apple lid, press down a little.
Place the apples in an ovenproof dish (with a lid if possible) and cook in the oven at 180 ° C for 45 - 60 minutes. Vanilla sauce or rice pudding tastes good with it.
