Chocolate has its origin in Mexico, where the god Quetzalcoatl gave, according to legend, the cocoa tree to men, which years later would be baptized with the scientific name Theobroma Cacao, which means "food of the gods" in Greek.
Cocoa was a food of great importance in Aztec society and was also used as a currency. They drank it liquid and mixed with spices. The result was a very energetic, dark, thick and frothy drink called "tchocolatl", a name that differs little from our "chocolate".
