Why are they called Pork Tenderloin?
The pork tenderloin, also called pork fillet or Gentleman’s Cut, is a long thin cut of pork.
As with all quadrupeds, the tenderloin refers to the psoas major muscle along the central spine portion, ventral to the lumbar vertebrae. This is the most tender part of the animal because these muscles are used for posture, rather than locomotion.
In some countries, such as the United States and the Netherlands (‘varkenshaas’), pork tenderloin can be bought as a processed product, already flavored with a marinade. A common American dish is a pork tenderloin sandwich (also called simply a “tenderloin”) – a very thinly sliced piece of pork, usually, the larger, tougher loineye (longissimus) muscle, which is battered or breaded, deep-fried, and served on a hamburger bun, usually with garnishes such as mustard, pickle, and onions.
