Peel and chop the onions. Finely dice the bacon. Clean, quarter, wash and remove the stalk. Chop or slice the cabbage into strips. Heat the lard in a large casserole. Fry the bacon in it until crispy.
Add onions, fry briefly and sprinkle with sugar. Caramelise while stirring until golden yellow.
Steam cabbage for about 5 minutes. Sprinkle with flour and sweat vigorously. Stir in 400 ml water, stock and vinegar, bring to the boil. Season with salt, pepper and possibly caraway. Cover and stew for 35-40 minutes.
Stir more often. Cook open for another 5-10 minutes. Season to taste. Serve with meat. Bread tastes good with it.
