A group of engineering students from Purdue University recorded that their licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. They tried the same licking test on 20 volunteers and found that the average licks to the center were 252 licks.

Fit a roasting pan with a roasting rack. Place roast on rack, fat side up, and cook in oven for 20 minutes. Without removing the roast, drop oven temperature to 325 degrees F and cook for an additional 60 minutes, or until internal temperature reaches 125 degrees F for a medium-rare finished roast.Remove roast from pan to a cutting board. If using a cooking bag to cook your prime rib, first sear all sides of the roast in a very hot pan with 2 tablespoons olive oil. 2  Preheat the oven to 325 degrees F, as you will not need the initial higher heat for browning.
