It is made from one of two different muscles located inside the chest and abdominal cavity, below the ribs, in the area of the cow referred to as the beef plate primal cut, which is a piece of the animal known as the skirt steak. The diaphragm muscle, also known as the outside skirt, and the transversus abdominis muscle, often known as the inside skirt, are the two muscles involved.
What is the difference between inside and outside skirt steak?
Because the inside skirt steak has a thicker grain contained in it, it contains more fat than the outer skirt steak, which is also why it shrinks more when grilled on the grill than the outside skirt steak. If you compare skirt steak to other cuts of beef, it has a looser texture in terms of muscle mass.
Should I Choose flank steak or skirt steak?
If you want your steak well done or tender, I recommend opting with flank steak instead. Both the outer and inside skirts contain a significant quantity of fat between and between the muscle strands, which helps to keep the meat juicy when grilling. Because the grain on the inside skirt is a little wider, it may have a little more fat than the outside skirt.
