Rib Eye New Potato And Portobello Kebabs With Rosemary Food

STANDING RIB ROAST WITH POTATOES AND PORTOBELLO MUSHROOMS

Steps:

• Preheat oven to 475°F.
• Make seasoning mixture:
• In a small bowl stir together seasoning mixture ingredients. Put roast, ribs side down, in center of a flameproof roasting pan, 18 by 12 by 2 inches, and rub oil on top and sides of beef so herbs will adhere. Reserve
• 1 tablespoon seasoning mixture and rub remainder on top and sides of beef. Roast beef in lower third of oven 20 minutes.
• Peel potatoes and halve crosswise. Remove pan from oven and skim all but about 1/2 cup fat from pan with a bulb baster or spoon. Arrange potatoes around beef and turn with tongs to coat with fat. Season potatoes with salt and pepper. Reduce heat to 350°F. and roast beef and potatoes, turning potatoes occasionally to brown evenly, 1 1/2 hours, or until a meat thermometer inserted in fleshy part of beef registers 130°F. for medium-rare.
• While beef and potatoes are roasting, separate mushroom stems and caps. Slice caps 1/3-inch thick. In a food processor pulse stems until chopped coarse and in a small saucepan combine with broth and water. Simmer mixture 10 minutes. Pour mixture through a sieve into a bowl, pressing hard on solids, and discard solids.
• Transfer beef to a platter and let rest, covered loosely with foil, 20 to 30 minutes. Transfer potatoes to another platter and keep warm.
• With bulb baster or spoon skim all but about 1/4 cup fat from pan. In pan on top of stove sauté mushroom caps over moderately high heat, stirring, 2 minutes. Add reserved tablespoon seasoning mixture, mushroom liquid, and any juices from beef and boil 5 minutes. Stir in beurre manié and boil, stirring, about 3 minutes, or until thickened slightly.
• Serve beef with sauce and sprinkle potatoes with parsley.
