Cuts · UK butchery

Rack of lamb

The rib chops left joined as one piece, usually trimmed so the bone ends are exposed. Small enough to cook like a thick steak rather than like the roast it resembles.

Known as

The same muscle carries different names in different butchery systems, and some of those names mean different cuts elsewhere. Where a name is ambiguous, BBQHQ says so rather than picking one.

United Kingdom: Rack of lamb
United States: Lamb rib roast

What to ask a butcher for

United States: Rack of lamb, French trimmed if you want the bones exposed.

Where it comes from on the animal

Lamb loin and rack
Back · low use · connective tissue: low
The back muscle, sold as loin chops with the bone or as cutlets from the rack. Tender, quick, and the cut AHDB gives grilling times for by thickness.
Muscles: Longissimus dorsi

Asking a butcher for it

Named the way uk butchery names it. If the counter does not recognise the name, the anatomy is the fallback: ask for the cut by where it comes from.

What to say: Rack of lamb, or Lamb rib roast (US) depending where you are.
If that draws a blank: Ask for back — the muscle is Longissimus dorsi.
What to specify: Thickness, which governs the timing more than weight does — the usual range is 40–60 mm. Typical weight is 500–900 g.

What it is suited to

Derived from how hard the muscle works and how much connective tissue it carries, which is the pairing that decides whether a cut wants a fire under it or beside it. BBQHQ does not rank cuts and does not name a best one.

Low connective tissue: there is nothing here that a long cook would improve. Direct or two-zone heat, taken off at a doneness rather than at a texture, and every extra minute past that point costs moisture.
A supporting muscle that does little work, so it is tender to begin with and has nothing to gain from time.

BBQHQ holds cooking evidence for this cut as rack of lamb.

What to use instead

BBQHQ has established no substitute for this cut. That is a statement about what has been checked rather than a claim that none exists.

Asking for it in another country

BBQHQ has not established how this cut maps to other butchery systems.

The UK side of these mappings rests on AHDB’s published cutting specifications, which BBQHQ has read. The US side does not: USDA’s Institutional Meat Purchase Specifications and the Beef Checkoff cut pages both refuse automated access, so no mapping here reaches “same cut” across two butchery systems. See the open question.
