Cacao (pronounced cah-COW) seeds were used to make ceremonial beverages
consumed by elites of the Aztecs and other civilizations, while also being used
as a form of currency.
The Spanish conquistadors who
shattered the Aztec empire in the 16th century were smitten with a chocolate
beverage made from cacao seeds served in the palace of the emperor. However,
this was not the form in which cacao had its beginnings.
"The earliest cacao
beverages consumed at Puerto Escondido were likely produced by fermenting the
sweet pulp surrounding the seeds," the scientists wrote in the journal
Proceedings of the National Academy of Sciences.
One of the researchers,
anthropologist John Henderson of Cornell University in Ithaca, New York, said
cacao beverages were being concocted far earlier than previously believed --
and it was a beer-like drink that started the chocolate craze.
