A skirt steak is a long steak taken from the 'plate' - between the brisket and the flank. It is most similar to a flank steak, although admittedly less tender. Skirt steak is used most often in stir-fry meat and in fajitas as thin, flat strips.
Flank steak can be flash-fried in a pan, as well as braised, or cut into strips.
Skirt steak makes a delicious, tender cut of beef for a quick dinner or a favorite meal.
