Amira picked up this delicious beverage at a local market here in Oaxaca. It's called Tejate and it's made with corn and chocolate.
Locals were drinking this stuff long before the Spanish arrived in the New World.
That stuff on top is made with flor de cacao, which is a local tree. It's really delicious, and has the consistency of butter and the taste of very mild chocolate.
I had it for the first time, and now I'm a huge fan.
