A5 Sirloin
Quiet confidence, remarkable flavor
Meticulously marbled and made for a swift sear. For anyone who wants extraordinary depth of flavor without the fanfare.
01
THE ANATOMY
Origin
Sirloin comes from the hindquarter, in the area just before the round. Exact cutting boundaries and names vary between national butchery systems.
02
THE STORY
Name and history
How it got its name
The word developed from Middle French 'surlonge': 'sur' means over, while 'longe' refers to the loin. The popular tale that a king knighted the meat as 'Sir Loin' is entertaining wordplay, not supported etymology.
How it reached the modern table
English first used forms such as 'surloin' before the spelling shifted to 'sirloin'. The change encouraged the later knighting legend, although the documented French roots explain the name directly.
03
THE SIGNATURE
Marbling
Sirloin is often leaner than ribeye, but an A5-graded Japanese carcass can produce exceptionally marbled sirloin. A5 describes carcass yield and quality grades; it is not the name of a breed or cut.
04
THE MOMENT
Best for
Thin or moderate portions cooked swiftly over high heat. Keep seasoning restrained, sear both sides, and slice across the grain so the beef remains the focus.
