Roger Mooking visits two chefs from Texas who love to play with smoke and fire in their restaurants and in their backyards. By day, Tom Spaulding serves classic Texas-style barbecue at his restaurant Live Oak. But for special occasions, Tom builds a grill out of cinder blocks and a metal sheet and grate for a South American parilla-style spread. At Chicken Scratch restaurant in Dallas, Tim Byres spins spice-rubbed chickens from his unique wood-burning rotisserie. But in the middle of his vegetable garden, Tim has dug a deep hole and lined it with bricks to make delicious Mexican Lamb Barbacoa inside and Pork Carnitas on top.
