Flank steak is a cut of beef taken from the abdominal muscles or lower chest of the steer. French butchers refer to it as bavette, which means "bib". Similarly, it is known in Brazil as fraldinha (literally: "little diaper"). The cut is common in Colombia, where it is known as sobrebarriga ("over the belly").
A relatively long and flat cut, flank steak is used in a variety of dishes including London broil and as an alternative to the traditional skirt steak in fajitas. It can be grilled, pan-fried, broiled, or braised for increased tenderness. Grain (meat fibre) is very apparent in flank steaks, as it comes from a well-exercised part of the cow, and many chefs cut across the grain to make the meat more tender. It is frequently used in Asian cuisine, often sold in Chinese markets as "stir-fry beef", and is served in French cuisine as an at most medium-rare steak. Flank also serves as a common cut for steak jerky.
