Chocolate comes from the beans of the cacao tree that grows in tropical climates.
The word cacao has been traced to the Olmec. The Maya continued the use and introduced this to the Aztecs who called it xocolatl, meaning 'bitter water.'
The Spaniards sent chocolate to Europe. It took a while for the treat to become popular. By the late 18th century chocolate shops were fashionable and chocolate has ever since been a world-wide favorite.
