Chocolate is a preparation of roasted and ground cacao seeds that is made in the form of a liquid, paste, or in a block, which may also be used as a flavoring ingredient in other foods. The earliest signs of use are associated with Olmec sites (within what would become Mexico’s post-colonial territory) suggesting consumption of chocolate beverages, dating from 19 centuries BCE. The majority of Mesoamerican people made chocolate beverages, including the Maya and Aztecs. The word chocolate is derived from the Spanish word chocolate, deriving in turn from the Classical Nahuatl word xocolātl. The most common colour of chocolate is brown but in can come in many other colours too!
