The prized skirt steak comes from the diaphragm muscles of the animal, attached to the 6th through 12 ribs on the underside of the short plate subprimal. It's a long, thin cut of beef, and is often confused with its neighbor, the flank steak, but has an even more intense and beefy flavor. Cook the skirt steak to rare or medium rare, and cut against the grain when serving. We recommend this recipe:

Prepare a grill for medium-high heat; oil grate. Remove steak from marinade, pat dry, and grill, turning once, until browned and medium-rare, about 4 minutes. Transfer to a cutting board and let rest 10 minutes. Thinly slice and top with chives and a sprinkle of sea salt.
