Cocoa beans as currency?
The Mayans praised chocolate as the drink of the gods. Mayan chocolate was a revered brew made of roasted and ground cacao seeds mixed with chillies, water and cornmeal. Mayans poured this mixture from one pot to another, creating a thick foamy beverage called “xocolatl”, meaning “bitter water.”
By the 15th century, the Aztecs used cocoa beans as currency. They believed that chocolate was a gift from the god Quetzalcoatl, and drank it as a refreshing beverage, an aphrodisiac, and even to prepare for war.
