Acorn-fed Iberico Pork Diaphragm is known as Diafragma Iberico de Bellota. It is derived from natural, antibiotic-free pork meat. This cut is reminiscent of a skirt steak cut and is similarly notorious for its slightly grainy and chewy texture. Its rich taste proves it to be a great substitute for beef skirt steak. It is perfect for many recipes, some ideas include using it to create pork fajitas or stir fry. It is really tender, so it does not need to be cooked to more than a medium-rare temperature.
