The Aztecs may have created the first viable chocolate industry because they didn't grow cocoa but traded for it. Chocolate was so rare that the expense of getting this amazing fermented, heated drink made it only reachable for the wealthiest horndogs in the Aztec upper east side. I just imagine the poor little Aztec servants firing up the water heater, ( I wonder who even handled their water heater installation), mixing the chocolate with hot water and melting the potent drink until it was a silky smooth nectar from heaven. In fact, it was so highly regarded and expensive that they drank it from the golden cups, which were then discarded rather than used for something less noble.
The Aztec king Montezuma was said to take 50 cups per day and extra cups when he engages on a romantic rendezvous. Its aphrodisiac effects were considered so strong that Aztec women were forbidden to drink it for fear of possible promiscuity. Actually, they probably just would have had a more pleasant time during PMS.
