Chocolate
One vessel found at an Olmec archaeological site on the Gulf Coast of Veracruz, Mexico, dates chocolate by pre-Olmec peoples as early as 1750 BC. On the Pacific coast of Chiapas, Mexico, a Mokaya archaeological site shows evidence of cocoa beverages from 1900 BC. The residues and the kind of vessel in which they were found suggest the initial use of cocoa was not simply as a beverage, but as a source of fermentable sugars for an alcoholic drink.
