>Considering that a turkey is typically cooked for a large group of people, not a single family, I'd say the average is 20-25lbs. Many cook it outside to leave the oven available for cooking the side dishes (and warming the ham). Today my friend roasted a 26lb turkey for 15 people. Nowadays I usually just cook a turkey breast and have cold turkey sandwiches for a couple of days afterwards. Yum.
What were the sandwiches on if they had to go cold turkey?
