Popeseye steak is thinly sliced rump steak, originating in Scotland.
The etymology of the term "popeseye steak" is twofold: One first begins with a cut of rump steak.
Slice width varies; one Scotch Beef butcher sells slices that "typically weigh around 6oz"[2] each.
Popeseye steak is very tender,[3] and, due to its relative thinness compared to other steaks, cooks quickly, particularly if used as a pan frying steak.
Cooking of this cut should stop as soon as it is brown on each side.
