Cut the meat into slices that are thin rather than thick. Mince two big onions and fry them till brown; then fry the slices till they are colored on both sides. Pour on them first some beer, then a dash of vinegar, adding thyme, pepper, and salt, and throw in also a slice of crust of bread, which you have spread with mustard. Let this all simmer for three hours.
