Red cabbage and apple casserole

• 1 1/2 pounds red cabbage

• 1 1/4 cups plain yogurt
• 1 tbsp creamed horseradish

Preheat the oven to 300°F. Shred the cabbage finely, discarding any tough stalks. Mix with the onions, fennel and caraway seeds in a large bowl. Peel, core and chop the apples, then stir them into the cabbage mixture. Transfer the mixture to a casserole dish. Mix the yogurt with the creamed horseradish. Stir the yogurt and horseradish mixture into the casserole, season with salt and pepper and cover tightly.  Bake for 1 1/2 hours, stirring once or twice during cooking. Serve hot, with rye bread.
