Rack of lamb

A rack of lamb, also known as carré d'agneau or best end, is a lamb cut that is perpendicular to the spine and includes 16 ribs or chops. In retail, it is commonly sold as a 'single' rack, which means it is sawn longitudinally and includes the eight ribs on one side only. However, it may also be sold as a "double rack of lamb," with ribs on both sides. Another presentation involves placing two French trimmed racks together with the ribs interlinked, which is often referred to as a "guard of honour".
Rack of lamb is typically roasted, sometimes with a coating of herbed breadcrumb persillade. To enhance the presentation, the tips of the bones are occasionally decorated with paper frills known as manchettes.

Crown roast

Two or three single racks of lamb tied into a circle make a "crown roast of lamb". Crown roasts are sometimes cooked with stuffing in the middle.

Frenching

Rack of lamb is often French trimmed, that is, the rib bones are exposed by cutting off the fat and meat covering them. Typically, three inches of bone beyond the main muscle are left on the rack, with the top two inches exposed.
