It is essential to place the meat on a rack inside a roasting pan so the meat is elevated off the bottom of the pan. This will allow the heat in the oven to circulate all around the meat as it cooks. I count about 15 minutes per pound at 350 degrees F for the meat to cook. I cook it until it achieves an internal temperature of about 135 degrees F. So juicy! The Yorkshire pudding, which is traditionally made with beef drippings, tastes better to me made with unsalted butter.
