It's a barefoot-on-the-beach dinner party cooked, served and eaten outdoors. But the catch of the day is ... there's no beach! Instead, Rick and his family create a little Mexican seaside nirvana right in their Chicago backyard, complete with a cabana improvised from billowing white curtains, muslin draped overhead, white table linens, sparkling Mexican candles and orchids. And the food is as inviting as the mood, because it all comes from the grill, starting with Rick's Grilled Garlic and Orange Guacamole, which gets its smoky flavor from flame-seared onions, garlic and jalapenos. Then come Grilled Mussels, cooked right on the grill grates, topped with tomatillo salsa and served as a passed appetizer. The main event is succulent Grill-Roasted Whole Fish Adobado marinated in sweet-spicy ancho chile adobo, grilled and served whole and sizzling, with a potatoes and onions, cooked in a "hobo-pack" right on the grill. Even the dessert gets the "beach-barbecue" treatment-it's homemade Grilled Cornmeal Pound Cake toasted on the still-warm grill and served with ice cream and fresh fruit salsa. Rick even provides a playlist of Latin favorites to match the mood. Conclusion: with a few good recipes and a little imagination, a Mexican seaside fiesta is just a barbecue and a boombox away.
