Fry the onions in hot pork or clarified butter. Steam red cabbage cut into strips. Season with cloves, bay leaves, sugar, salt and pepper. Cut the vanilla pod lengthwise and scrape out the pulp.
Add both with 1 peeled diced pear, 400 ml water and red wine vinegar to the red cabbage. Bring to the boil, cover and stew for about 2 hours. Stir in 1 peeled pear in slices about 15 minutes before the end of the cooking time with black currant jelly.
Season to taste red cabbage.
