I usually cook a larger quantity than can fit in a crock pot or even a pressure cooker. Back MANY years ago in high school I worked in the kitchen the largest Truck Stop up here and the chef used to do it the same way but in much larger quantities, like 6 in a huge roaster with all the vegs. Pretty much set it and forget it for an hour and I got elected to baste. But it always sold out. We only offered the week of St. Patricks Day, as everyone was tired of it after that. And I am already getting tired of the leftovers...lol
