Combine all the spices. Make slits about an inch deep at 1-inch intervals in the roast. Rub spice mixture into the slits and over the roast surface. Place roast in a covered pan in 2 inches of water (I use beef broth instead, adds another great flavor). Insert meat thermometer in center of the roast. Bake at 350 degrees for 1 ½ to 2 hours of until thermometer says 160 degrees.
