From Texas

Inside skirt steaks are cuts taken from the short plate, and often confused with the outside skirt steak. The biggest difference between the two is that the inside skirt steak is a much longer cut from inside the chest wall. Because this muscle works hard, it takes well to marinades and quick cooking methods that help tenderize its thick fibers. It has an incredibly rich beefy flavor that is perfect for making mouth-watering fajitas.
