Chocolate is a product of roasted and ground cacao. The earliest signs of use are dating from 19 centuries BC. The majority of Mesoamerican people made chocolate beverages, including the Maya and Aztecs. The history of chocolate began in Mesoamerica. Fermented beverages made from chocolate date back to 450 BC. The Aztecs believed that cacao seeds were the gift of Quetzalcoatl, the god of wisdom, and the seeds once had so much value that they were used as a form of currency. Originally prepared only as a drink, chocolate was served as a bitter liquid, mixed with spices or corn puree. It was believed to be an aphrodisiac and to give the drinker strength. After its arrival to Europe in the sixteenth century, sugar was added to it and it became popular throughout society. Today, chocolate has many different uses. It is also the favourite sweet of children and it sells in various stores around the world.
