Flank refers to a cut of meat taken from the underside of the cow or lamb, known for its robust flavor and distinctive texture. It has a long, flat shape and distinctive grainy texture. While flank steak is flavorful, it can be tough if not cooked properly. Therefore, it is best prepared using high-heat cooking methods such as grilling, broiling, or pan-searing. Flank steak is often marinated before cooking to tenderize the meat and enhance its flavor. Once cooked, it should be thinly sliced against the grain to maximize tenderness.
