Cut pork into 1/2" cubes and dust with flour, salt and pepper. In a heavy hot iron skillet, on your side burner, add the oil. On medium heat, add pork and brown. Add onions and garlic, cook and stir for 5 minutes. Pour off any drippings. Stir in parsley, bay leaf, broth, beer, vinegar and brown sugar. Lower heat, cover and simmer for 1 1/4 hours or until pork is tender, stirring occasionally.
Serve with buttered noodles, rye bread and red cabbage.

Works equally well with beef cubes.
