Roger Mooking visits two Southern California barbecue joints that serve smoked meat specialties on weekends only. First, he meets a husband and wife team running a pop-up restaurant called Moo's Craft Barbecue in their own backyard. He helps load their 2,000-pound smoker with Texas brisket and pork butt for tasty tacos and samples their signature side dishes, Mexican street corn and coleslaw kicked up a notch with tequila. Then Roger finds Calabasas Custom Catering in the parking lot at Jim's Fallbrook Market. He helps caterer Paul Varenchik fire up a big Santa Maria grill to cook beef tri-tip, chickens and baby back ribs, and the waiting customers complete their barbecue plates with crusty garlic bread, macaroni salad and potato salad.
