Preheat oven to 450 degrees F.
Prepare lamb for roasting. Place any trimmed-off bones in the bottom of a roasting pan. Place the meat, fat-side up, on top of the bones. Season with salt, pepper and thyme.
Place in hot oven and roast to desired doneness. Rack of lamb is usually roasted rare or medium. Test doneness with a meat thermometer or by the touch method as for steaks. Total time will be about 30 minutes.
Remove the lamb from the roasting pan and hold in a warm place. Leave bones in the pan. Set the roasting pan over moderate heat to caramelize the juices and clarify the fat. Pour off the fat. Add the garlic to the pan and cook 1 minute.
Deglaze the pan with the stock and reduce by half. Strain, degrease, and season, to taste. Cut the meat between the ribs into chops. Serve 2 chops per portion with 1 ounce of juice.
