Barbecue is about as old as mankind itself: All you need is fire and meat. Doesn’t get more primal than that. Just ask Matt Adboo and Shane McBride, the team behind the sprawling Gowanus BBQ eatery Pig Beach. The two join the podcast to discuss the expansion of their meaty empire, their fine dining past (Balthazar, Del Posto), and their new book, “The Pig Beach BBQ Cookbook: Smoked, Grilled, Roasted and Sauced.”
