Roger Mooking heads to the South to visit two family-run barbecue joints that have been passing down recipes and rigs for generations. At Smokin' Joe's Bar-B-Que in Townsend, Tenn., pitmaster Zack Peabody honed his barbecue chops under the watchful eye of his grandfather, Joe Higgins. Zack and Joe built a smoker that can cook up to 1,000 pounds of meat, and Roger and Zack arrange briskets and pork butts on its shelves. At Shack in the Back BBQ in Fairdale, Ky., Mike and Barbara Sivells converted an old log cabin into a barbecue restaurant. Roger and Mike load pork shoulders and turkey ribs into the smoker to create two popular dishes: The Hump and Turkey Ribs.
