Your guests will be delighted by this luxurious (and expensive) lamb dish. Racks of rib chops are roasted with a sweet and tangy glaze then sliced and served.Preheat oven to 450° F. Make slits in meaty parts of lamb and insert garlic slivers. Set lamb in a shallow baking dish, brush with Silver Palate Sweet and Rough Mustard and season with salt and pepper. Place in oven, reduce heat to 350° F. and roast for 20 minutes for medium-rare. Remove from oven and let rest for 5 minutes. Carve into chops and arrange on a serving platter or individual plates. Garnish with watercress sprigs. Start the meal with a simple pasta course and serve the lamb with a bottle of fruity merlot.
