2. Histo ry o f Chocolate

Dates back to about 1,500 years ago.

First found in Mayan and Aztec Civilizations.
•
Mayans used cacao beans to create a cold, unsweetened, spicy
chocolate beverage. This was the first form of chocolate.
•
Aztecs came across cacao beans through trade. They named the
spicy drink xocolatl (bitter water).
•
Cacao beans played important roles in both Mayan and Aztec
Civilizations.
This scene was painted on an ancient
Maya vessel, which reveals how
people drank chocolate as a beverage

and often presented it to their gods as
an offering.
Spanish conquistador, Hernan Cortes
•
In the late 18th century, French and
Dutch processors experimented with
chocolate liquid.
–
This lead to the production of
chocolate powder, which then led
to the production of the first
solid chocolate.
–
The first solid chocolate was
believed to have been sold in
England
