A thick slice of lean beef cut for grilling or frying, the quintessential centerpiece of meat-centered meals. The term covers the great grilling cuts, ribeye, sirloin, fillet, and rump, each with its own balance of tenderness, flavor, and fat. Cooking is a study in heat management: a fierce sear builds the caramelized crust of the Maillard reaction while the interior is brought precisely to the desired doneness, from blue to well-done. Resting after cooking redistributes the juices, the step impatient cooks skip to their regret. Nutritionally it delivers complete protein, heme iron, zinc, and B vitamins in a dense package, which is why dietary guidance treats it as a valuable but moderate-portion food rather than a daily staple.
