Where it's from: Skirt steak is a thin, long cut of beef from the diaphragm muscles of the cow. It is also lean and contains a lot of tough fibers. Flavor and texture: Skirt steak has even more intense beefy flavor than flank steak.
I agree with the previous answer: FLANK STEAK (or fajita steak since it is most often used in fajitas due to the texture, thickness, cost effectiveness, etc). Skirt or Flank Steak is a boneless cut of beef from the lower part of the brisket.efinition: Cut from the beef flank, the skirt steak is the diaphragm muscle (which lies between the abdomen and chest cavity).
