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.

1 After 20 minutes turn the oven down to 325 degrees F. and roast until the desired internal temperature is reached (see guide below). 2  For medium-rare this will take approximately 15 minutes per pound. 3  Transfer to a large platter, and let the prime rib rest, loosely covered with foil for 30 minutes before serving. Rub the entire surface of the cold roast with butter, and coat evenly with the kosher salt and black pepper. 2  Leave the prime rib out at room temperature for 2 hours. 3  Preheat the oven to 450 degrees F. 4  When the oven is hot, put the roast in and cook for 20 minutes to sear the outside of the roast.
