Peel and finely chop the onion. Also peel and core the apple and cut into small cubes.
Heat the crackling lard in a saucepan and fry the onion and apple cubes in it until golden. Add the sauerkraut with the juice from the can, the apple juice, the broth, juniper berries, bay leaf and caraway seeds. Season with salt and pepper. Then comes the meat.
Turn down the temperature and let it simmer gently for two hours with the lid on.
