The word sirloin was derived from the Old French word surlonge, meaning sur la longe or above the loin. Sirloin is the piece of beef between the rump and the ribs. Coming from an area of the animal where the muscles do less work, the sirloin is tender and flavourful and well suited to BBQ or grilling. If you don’t feel like a Steak though, this cut can also be sliced into stir-fry strips.
