Chocolate dated to 1000 CE in North America

Chocolate was drunk in North America as early as 1000 C.E., according to an article posted at LiveScience magazine online. The article describes cacoa residue found inside carved cylinder tubes in northern New Mexico.

Because cacoa won't grow in North America, it is believed that the beans were imported, and the drinking of cacoa may have been part of a ritual. Researchers at the University of New Mexico and the Hershey Center for Health and Nutrition conducted the study of the cacoa residue.
