Standing Rib Roast (Chef Anne Willan)

I got this from the Martha Stewart web site. It is amazingly delicious! Be sure to check the recipes for Roasted Potatoes, Yorkshire Pudding and the Horseradish Sauce.

• Ready In: 1 hr
• Serves: 6-8

Ingredients

• 7 -8  lbs  rib roast, with 3 to 4 ribs, trimmed
• 2  teaspoons mustard, dry
• 2  teaspoons sugar
• 2  teaspoons Dijon mustard
•  salt and pepper
• 2  tablespoons all-purpose flour
• 2  cups  beef stock

Directions

1. Remove excess fat from roast, leaving just a thin layer.
2. In small bowl, combine dry mustard, sugar, and Dijon mustard. Brush mixture over fat and cut surfaces of roast. Refrigerate 2 hours to overnight.
3. Set roast, rib-side down, in heavy, shallow roasting pan in 450 F oven. (Ribs act as a natural rack.) With a paring knife, score the fa and season with salt and pepper.
4. Roast 15 minutes. Reduce heat to 350 F and continue to roast (basting every 15 minutes) until temperature reaches 125 F (medium rare). Remove roast to a platter. Let rest for 15 minutes before carving.
5. GRAVY: Keep 2 tablespoons of fat from roasting pan. Set it on stove over medium heat and simmer until juices begin to darken, 1/2 minutes. Whisk in flour and cook, scraping up caramelized bits, until flour is deep golden brown, 3 minutes. Add stock and bring to boil, stirring until thickened. Season with salt and pepper.
