How Do You Calculate Cooking Time For Prime Rib?
To calculate cooking time for prime rib, you need to measure the weight of the prime rib and calculate its cooking time by multiplying the weight in pounds with a cooking time of 15-20 minutes per pound. For example, if the prime rib weighs 5 pounds, it will take approximately 1 hour and 15 minutes to 1 hour and 40 minutes to cook. It is important to use a meat thermometer to check the internal temperature of the prime rib and ensure it reaches an internal temperature of 135°F for medium-rare, 145°F for medium, and 155°F for well-done.
