A Quick History Lesson on Skirt Steak and Why It’s So Expensive Today
Skirt steak used to be considered offal (refuse or waste) or “organ” meat.
Cattle Ranchers in the American South would give these tough cuts of meat to field workers – typically of Mexican origin.
In these fields is where skirt steak gained popularity as the famous “arrachera” and became a key ingredient in dishes of Mexican inspiration like fajitas and steak tacos.
The word fajita is Spanish for “little belt.”
The skirt steak is a thin cut of meat that resembles a sash, girdle, belt, or skirt.
Skirt steak is also very popular in Argentina for similar reasons. Cattle ranchers would enjoy skirt steak or “entraña” (which translates to entrails or “guts”) as part of their asados.
These days this stigma is gone and since there are only 4 skirt steaks on a cow and 2 go to restaurants, they’re expensive for regular people.
