The word 'sirloin' comes from the French 'surlonge', meaning 'above the loin'. However, the popular story of the origins of this word describe how a king of England thought this cut of beef was so superior that he felt moved to knight it - dubbing it 'Sir Loin'.
The sirloin is the ideal roast for flavour and tenderness; however, it is also the most expensive. It may be sold in a single piece for roasting, either on or off the bone or cut into steaks for grilling or frying.
