Korean beef short ribs are also called L.A. or Miami ribs. If you can't find these ribs in your supermarket, ask your butcher to cut regular beef short ribs across the bone into 1/4- to 1/2-inch-thick pieces.
Substitute 1 flank steak (2 lb./900 g) for the ribs. Refrigerate in marinade as directed, then grill 8 to 10 min. or until medium doneness (160ºF), turning after 5 min. Cut across the grain into thin slices to serve.
