We find Rick and his daughter, Lanie, at the Mexico City's colorful Sonora Market, an emporium of medicinal herbs and the best place in town to buy cazuelas, the beautifully rustic earthenware cooking and serving casseroles that define a whole class of stews and taco fillings. We tend to think of taquerias for their familiar grilled and griddled fillings, like carne asada. But, Rick explains, there's a whole world of stands and shops that have no grill at all and specialize in satisfyingly homey, slow-cooked fillings made in cazuelas with everything from stewed meat to richly flavorful vegetables. Rick and Lanie check out El Guero, a Mexico City institution, popularly known as "Tacos Hola!," that specializes in slow-cooked taco fillings. Back home in Chicago, Rick and Lanie plan a cazuela-taco dinner. Lanie throws together a quick Pork with Smoky Tomato Sauce and Potatoes in the crockpot before heading off to school. By dinnertime, it'll be meltingly tender and richly flavored. Meanwhile, Rick gathers some chard in the garden, offering a quick intro to the care and tending of this hearty, easy-to-grow vegetable. Then, he turns his harvest into a filling of Creamy Braised Chard, Potatoes and Poblanos and also prepares a Veracruz-Flavored Chilled Seafood. The three fillings, mounded in those charming cazuelas from the Sonora Market, form the centerpiece for a cozy dinner with friends and family.
