The outside skirt, known as ハラミ (harami) in Japanese, is a beef cut taken from the diaphragm muscle of the cow. It is a long, flat piece of meat, known for its rich flavor and tenderness. The outside skirt is located near the cow's belly, specifically between the chest and the abdominal muscles. This cut is favored for its marbling and the intense beefy taste it provides. It's often used in grilling and barbecuing due to its ability to retain flavor and moisture when cooked over high heat. Popular dishes include fajitas, Korean bulgogi, and Japanese yakiniku.
