Fatback is a cut of meat from a domestic pig. It consists of the layer of adipose tissue (subcutaneous fat) under the skin of the back, with or without the skin (pork rind). Fatback is "hard fat", distinct from the visceral fat that occurs in the abdominal cavity and is called "soft fat" and leaf lard.Like other types of pig fat, fatback may be rendered to make a high quality lard, and is one source of salt pork.
