Salt and pepper the meat and fry brown all over in foaming butter. Peel and roughly dice the onion and carrot, add to the meat and fry for another 3 minutes. Add bay leaves, cloves, peppercorns, vinegar, red wine and jam, cover and simmer for 1 1/2 - 2 hours over low heat, turning 2 - 3 times. Slice the cooked roast.
Strain the sauce and season to taste sweet and sour, pour over the meat.
Bread dumplings and red cabbage taste best as a side dish.
