Prime Rib with Horseradish Cream

Directions

1. Place roast fat side up in a shallow roasting pan. Cut slits into roast; insert garlic slices. Sprinkle with pepper. Bake, uncovered, at 450° for 15 minutes. Reduce heat to 325°; bake 2-3/4 to 3-1/4 hours longer or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°).
2. Meanwhile, in a small bowl, beat cream until soft peaks form. Fold in the horseradish, vinegar, mustard, sugar, salt and pepper. Cover and refrigerate for 1 hour.
3. Remove roast to a serving platter and keep warm; let stand for 15 minutes. Serve with cream.
