Overview: The Baylesses love to feed a crowd. And one of their favorite ways to do it is firing up the Mexican-style barbecue pit they built in their Chicago backyard, inspired in part by the 3,000 seat Arroyo restaurant in Mexico City, where the pit-cooked lamb and pork make every meal a carnivore’s carnival ride. At Arroyo, we catch a glimpse of barbacoa—lamb wrapped in maguey leaves, slowly roasted in a massive brick pit. And with that mouthwatering memory in mind, Rick and his daughter, Lanie, prepare a block party for 25, featuring Oaxacan-style Barbacoa—lamb marinated with red chiles, wrapped in avocado and banana leaves and slow-roasted in the smoldering pit. To welcome the lucky friends and neighbors, there are refreshingly simple Watermelon Coolers and freshly made Tlayudas Oaxaqueñas, Oaxacan-style grilled tostadas, topped with chorizo, guacamole and fresh cheese.
