Prepare the roast your favorite way - rubbing with spices, Worcestershire sauce, salt, lemon pepper, grated ginger, etc. Place in preheated 500 degree oven and cook 3-5 minutes per pound. Trial and experience must be your guide. Weight, tenderness, and thickness to the center of the cut determines the time per pound. Try 5 minutes for average. After cooking as above, turn off oven. THE OVEN DOOR MUST NOT BE OPENED FOR TWO FULL HOURS. Not even a quick peek. The roast will come out rare and pink from the outside to the center, and full of juices.
