Flank steak is a lean and flavorful cut of beef that comes from the underside of the cow, specifically from the abdominal muscles. It is a long, flat cut that is characterized by its prominent grain and coarse texture. Flank steak is versatile and can be prepared in a variety of ways, such as grilling, broiling, or pan-searing. It is often marinated before cooking to tenderize the meat and enhance its flavor. Flank steak is also a popular choice for dishes like fajitas, stir-fries, and tacos due to its texture and ability to absorb marinades and seasonings. While flank steak is leaner than some other cuts of beef, it is still a good source of protein, iron, and other essential nutrients.
