where does skirt come from on a cow
Skirt steak Both the inside and outside skirt steak are the trimmed, boneless portion of the diaphragm muscle attached to the 6th through 12th ribs on the underside of the short plate. This steak is covered in a tough membrane that should be removed before cooking.
Strip steak The strip steak is a cut of beef steaks from the short loin from a cow. It consists of a muscle that does little work, the longissimus, making the meat particularly tender;[1] although not as tender as the nearby psoas major or tenderloin. Fat content of the strip is somewhere between the two cuts. Unlike the tenderloin, the longissimus is a sizable muscle, allowing it to be cut into larger portions.
