The smoke signals of fiery feasts lure Roger Mooking to the Southwest, where his first stop is West Alley BBQ and Smokehouse in Chandler, Ariz. The hot spot specializes in Tennessee-style barbecue, and Roger helps founder Bardo Brantley and Pit Boss Robert "Jim Dandy" Spann load brick pits with over 300 pounds of pork. The pork butts are piled high in their signature sandwich, The Big Jim Dandy, and their fan-favorite ribs are tossed in a barbecue sauce with a heavy hit of cayenne. For his second stop, Roger gets lucky in Las Vegas, where he meets Chef Justin Kingsley Hall of The Kitchen at Atomic. His portable rig known as "The Swing Set" is anything but child's play. To build this winning jackpot of meat, Roger and Justin suspend Mediterranean spice-rubbed legs of lambs, nestle butternut squash into a bed of coals and grill carrots in a swinging basket.

Roger Mooking meets two barbecue brainiacs who have mastered the art of marrying heat and meat to turn out top-notch barbecue.
