If you make the sauce, you would have to make the meat too.
Brown a pork shoulder (keep it in the pot). Add two sliced onions and five cloves. Cook that until the onions brown. Add about 2.5 ounces tomato paste and two tablespoons mustard. Cook that for about a minute. Fill the pot halfway will stock and cook until the pork shoulder is nice and tender.
Would Jäger bombs and a steak do?
