What is British back bacon?

British back bacon is bacon prepared in the English culinary tradition, defined by its cut, curing style, and role within an English breakfast rather than by geography or origin of the pig. It is cut primarily from the pork loin, sometimes with a small attached portion of belly, producing oval rashers with a lean central eye and a narrow strip of fat, with an emphasis on meat rather than fat. Back bacon is cured to create a savoury, pork-forward flavour without heavy sweetness or pronounced smoke and is intended to be grilled or fried and served as a principal component of the breakfast plate rather than as a crisp garnish. In the context of an English breakfast, the term "bacon" is understood to mean back bacon prepared in the English style, with other forms such as streaky bacon cut solely from the belly belonging to different culinary traditions and not regarded as equivalent.
