Not to be confused with Fatback. Roasted unsliced peameal back bacon Back bacon is a traditional British cut of bacon[1] sliced to include one piece of pork loin and one piece of pork belly combined into the same cut. The name refers to the cut of meat, which includes meat from the loin (or back), and distinguishes it from other bacon made from exclusively pork belly or other cuts. Like other bacon, back bacon can be brined, cured, boiled, or smoked. It is much leaner than American style bacon made only from the belly.
