MUSTARD-CRUSTED PRIME RIB WITH MADEIRA GLAZE

Steps:

• Let roast stand at room temperature for 1 hour. Preheat oven to 450°. Combine mustard, garlic, brown sugar, salt and, if desired, peppercorns; brush evenly over top and sides of roast but not over bones (mixture may seem loose but will adhere). Place bone side down on a rack in a shallow roasting pan. Place pan on middle oven rack; immediately reduce heat to 350°. Roast 1 hour., Toss potatoes, carrots, onion and fennel with next 5 ingredients. Arrange vegetables in a single layer in a 15x10x1-in. baking pan on lowest rack of oven. Roast meat and vegetables, stirring vegetables midway through baking, until meat reaches desired doneness (a thermometer should read 135° for medium-rare, 140° for medium and 145° for medium-well), about 1-1/2 hours. Cover roast loosely with foil during last 30 minutes to prevent overbrowning. Let stand 15 minutes before carving., Meanwhile, for glaze, combine balsamic vinegar, Madeira wine and brown sugar in a small saucepan. Bring to a boil over medium-high heat; cook until reduced to 1/2 cup, about 15 minutes. Let glaze cool to room temperature. Serve roast with vegetables and glaze and, if desired, pink peppercorns and fennel fronds.
