The double loin of lamb, which is joined along the backbone of the lamb, is called the saddle. Once the saddle is boned, these two loins can be cut into 3-cm thick slices and chargrilled or fried. These slices are called noisettes in French.
Place the saddle fat-side down, and cut off the flaps on either side of the backbone with a boning knife.
Holding the knife close to the bone, cut and scrape down both sides of the backbone to release the two slender fillets.
Cut each fillet crosswise into 6 even slices using a chef’s knife. Flatten each slightly using the side of the knife.
