Back bacon is a cut of bacon that includes the pork loin from the back of the pig. It may also include a portion of the pork belly in the same cut. It is much leaner than side bacon made only from the pork belly. Back bacon is derived from the same cut used for pork chops.[1] It is the most common cut of bacon used in British and Irish cuisine, where both smoked and unsmoked varieties of bacon are found.[2]
