For roasting, choose joints such as saddle, rack (joined cutlets), crown roast (what the French call carré d’agneau), guard of honour, loin, shoulder or leg. A loin (6–7 chops) will feed 3 people and a chop loin (4–5 chops) will feed 2 people.
Roast lamb is best cooked on the bone at 200°C (400°F/Gas 6). For pink meat, roast for about 20 minutes per 500 g (1 lb 2 oz), with 15 minutes extra at the end. For well-cooked lamb, cook for 25 minutes per 500 g (1 lb 2 oz) with an extra 25 minutes at the end.
If the skin and fat are not browned or crisp enough, grill them for a few seconds. A light covering of fat will baste the meat as it cooks, but serve on hot plates as lamb fat congeals quickly.
