Chocolate is a food made from roasted and ground cacao seed kernels that is available as a liquid, solid, or paste, either on its own or as a flavoring agent in other foods. The seeds of the cacao tree have an intense bitter taste and must be fermented chocolate apples develop the flavor.

After fermentation, the seeds are dried, cleaned, and roasted. With some two million children involved in the farming of cocoa in West Africa, child slavery and trafficking associated with the cocoa trade remain major concerns. Chocolate has been prepared as a drink for nearly all of its history. For example, one vessel found at an Olmec archaeological site on the Gulf Coast of Veracruz, Mexico, dates chocolate’s preparation by pre-Olmec peoples as early as 1750 BC.

Maya tomb from the site in Rio Azul had vessels with the Maya glyph for cocoa on them with residue of a chocolate drink, suggests the Maya were drinking chocolate around 400 AD. By the 15th century, the Aztecs had gained control of a large part of Mesoamerica and had adopted cocoa into their culture. The Aztecs were unable to grow cocoa themselves, as their home in the Mexican highlands was unsuitable for it, so chocolate was a luxury imported into the empire. Those who lived in areas ruled by the Aztecs were required to offer cocoa seeds in payment of the tax they deemed “tribute”. The Maya and Aztecs associated cocoa with human sacrifice, and chocolate drinks specifically with sacrificial human blood.
