The Skirt, or Diafragma as it is commonly known in Iberian pork in Spain, is a little used muscle that sits on the inside of the belly, on the diaphragm of the pig. We remove this little muscle when we bone out our bellies for curing. It is thin muscle with a plenty of intramuscular fat, making it a wonderful little steak for grilling.
We grill them over a hot grill, hard and fast, serving them just pink.
