Guarnaschelli's go-to is make-ahead Pork Osso Buco, a traditional Italian dish that uses a specific cross-cut of meat: a shank that exposes the bone in the center. The first step is to brown the meat in hot oil in a large Dutch oven or heavy-bottomed pot for up to five to eight minutes on each side, and once you remove the meat, add vegetables, wine, and tomatoes, and cook down a bit before returning the meat to the pot.
