The chocloate tree's scientific name, literally "food of the gods," refers to an ancient Aztec belief. They made a delicious drink of ground cocoa seeds with red peppers and water. The seed, or cacao "bean," also served as currency and continued to be used as money until the 1850s on the Yucatan Peninsula of Mexico. Chocolate is made by removing the seeds from the pods, roasting, grinding, then adding cocoa butter (from the seed oil), sugar, and sometimes milk.
