Anthropologists have discovered cacao residue in pottery unearthed at Chaco Canyon, raising questions about how and when the tropical bean got here, and how our Southwestern ancestors made use of the stuff. (My money's on chocolate fry bread, but maybe that's just wishful thinking.) Join the Maxwell Museum of Anthropology for A Place at Mother Earth’s Table, two days of thought- and hunger-provoking topics on food and culture. Friday opens up with an expert's take on the Chaco-cacao mystery at 7 p.m. in UNM's Anthropology Lecture Hall 163. Saturday brings a discussion of coffee, tea and chocolate beverages at 2 p.m. (same hall), followed by a tasting of of modern beverages that use ancient ingredients at 3 p.m. in Hibben Center.
