Origin
Frenching, the clearing of the rib bones of meat, fat and membrane, belongs to French butchery and to the professional kitchen, where the carré d'agneau is roasted whole or divided into côtes. Jacques Pépin sets the method out step by step in Complete Techniques, and it is carried today by the French butcher and the trained cook alike.
Description
The cut is the carré d'agneau, the rib section of the lamb (Ovis aries), usually of eight ribs, taken from the best end of the loin and sold with the chine bone removed or loosened. Trimming removes the excess surface fat and the sinew, leaving a thin even layer over the eye of the meat, the noix. Frenching then strips the upper part of each rib bone of meat, fat and membrane, so that the bones stand clean and white above the eye. The trimmings are kept for the fond, for a jus or for mince.
The Thread
Flavour Context
The roasted rack is served with a jus made from the lamb trimmings and bones, with flageolet beans, a gratin dauphinois, white haricots or a purée of vegetables, and often with rosemary, thyme and garlic. It is drunk with a red wine of structure, such as a Pauillac or a Saint-Émilion, because the tannin meets the fat and the sweet flesh of the lamb, which is delicate and needs a wine that cleans without overpowering it.
