Lamb loin chops
IMPS item 1232A, from any bone-in loin item, containing no hipbone. Called a T-bone chop when the tenderloin comes with it.
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 States
- Lamb loin chops
- T-bone chop
IMPS applies the name only where the tenderloin is present.
What to ask a butcher for
- United States: A loin chop with the fillet still attached.
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 us 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
- Lamb loin chops.
- 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 20–30 mm. Typical weight is 90–150 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.
What to use instead
A substitute is not the same as an equivalent. These are graded, because “yes, use that instead” is the answer that ruins dinners: most real substitutions work only once something about the cook changes.
Workable, once you change the cook
IMPS 1232A and the British loin chop are the same cut in outline. The American specification is tighter about what may be included.
- IMPS 1232A must contain no portion of the hipbone and constrains the flank edge to a specified tail length. British retail sets no such boundary.
- A British 'cutlet' is not this cut at all — it is the rack chop, IMPS 1204B/1204C.

UK butchery: Overlapping cut
IMPS 1232A and the British loin chop are the same cut in outline. The American specification is tighter about what may be included.
What differs
- IMPS 1232A must contain no portion of the hipbone and constrains the flank edge to a specified tail length. British retail sets no such boundary.
- A British 'cutlet' is not this cut at all — it is the rack chop, IMPS 1204B/1204C.
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.
