pachamanca, and the demonstration of how to prepare this ancient culinary feast was a highlight of the recent Latin Flavors, American Kitchens seminar at the Culinary Institute of America's San Antonio campus. The elaborate display showcased the school's new fire pit area and it drew dozens of viewers to watch each step. Pearl Brewery owner Kit Goldsbury and his wife, Angie, were among the excited onlookers and were thrilled to be a part of the ceremony, by placing the cross and flowers on the final pit as the cooking started. The red and white flowers represented the flag of Peru, while the cross was a means of giving thanks — not to bury it, said chef Marilu Madueño of Huaca Pacllana in Lima, Peru. She and her partner, Arturo Rubio, led the demonstration that included many of the school's students preparing the pit, making the tamales, peeling the yuca and marinating the meats. In Peru, the whole town gets together to celebrate and everyone does his or her part to make the meal happen, Rubio said. The process starts with placing the potatoes amid the ashes. Then the hot rocks are layered with the meats and vegetables, a process that has to be done quickly, Madueño says. That's so the meat will sizzle and sear on the rocks. Once everything is placed in the ground and covered with banana leaves, the whole pit is covered with damp soil so seal in the heat, Rubio said. The air around the rocks ensures the pit "works like a convection oven," he said. After the hour-long cooking process, someone pours a drink — usually pisco, but a beer or wine will do — over the mound as a blessing, Rubio said. The four corners of the earth are covered as the people give thanks for their cattle, their family, the harvest and Mother Earth. Cattle comes first, he joked, because without it the family would starve. The food is removed from the ground with the same ritualistic care as it took to create. But once removed, it is time to dig in and enjoy. Captions: 1. CIA student Todd Martin heats rocks over a wood-burning pit used for the Peruvian pachamanca. 2.
