Let roast stand at room temperature for 1 hour. Preheat oven to 500°F. Pat beef dry and season with salt and pepper to taste. Roast beef for 30 minutes. Reduce heat 300°F. Crush allspice and combine with black pepper, rosemary, oregano, thyme, coriander, salt, flour, mustard and butter to form a paste; spread on roast. Roast beef for 1 to 1-1/2 hours, or until meat reaches 135°F for medium rare. Rest 20 to 30 minutes before carving. Sauce: Combine cream, mustard, beef broth, pan drippings, shallots, rosemary, coriander and salt in a saucepan. Bring to a boil, and simmer 2 minutes. Add Grand Marnier and continue cooking an additional 5 minutes to reduce liquid. Serve over beef. Recipe Note: lightly crush rosemary leaves, if desired.
