When it comes to finding great barbecue, Roger Mooking knows that it's not just the small towns that dish out big flavors. He heads to Bludso's Bar and Que in Los Angeles, where owner Kevin Bludso brings meat and heat to Tinseltown in a big way. Using the cooking techniques his Texas grandmother taught him, Kevin loads up his massive smoker with brisket, pork ribs and chicken to cook low and slow in oak and pecan smoke. Kevin also shares his family's 70-year-old recipe for mac and cheese with Roger. In San Antonio, another big city stepping up its barbecue game, Roger meets with Emilio and Christi Soliz, who have turned a small house into a restaurant blending Texas-style barbecue with Tex-Mex flavors. They stuff slow-smoked brisket into torta sandwiches with crema and avocado, while fall-apart pork butt is piled onto corn tortillas with cilantro and salsa.
