 In ancient times, going all the way back to the Saxons, roasting a wild boar was often the centerpiece of a meal at Yuletide, with Yule being Freya's feast.The head was often the greatest delicacy, as evidenced by the survival of the Boar's Head Carol.In the United States, roasting a whole pig or a feral hog has been a tradition for over two hundred years, especially in the Southern United States where it is closely linked to barbecue.
