Bake for 15 minutes, then reduce the oven temperature to 325°F (165°C). Continue baking for 1 hour 30 minutes. Remove the meat from the oven when the temperature on the thermometer is 3 to 4 degrees below the desired doneness: 135°F (57°C) for rare, 155°F (68°C) for medium and 170°F (77°C) for a well-done roast. Wrap the meat in foil and let rest for 10 minutes.
