Five centuries ago, before Spanish conquistadors arrived, what's now Mexico City was the Aztec capital of Tenochtitlan—and it took the European invaders' breath away. It was built on an island threaded with canals; it was one of the largest cities in the world; and the Spanish could hardly believe the sheer volume of food sold in the city's main market, let alone the quantity and variety of dishes enjoyed by the Aztec leader, Montezuma. But how did a city built in a lake—and located in a part of the world without cows, sheep, pigs, or chicken—grow enough to feed quarter of a million people? What does it mean to eat like an Aztec, and can you still do it today? This episode, we're time traveling (and real traveling) to find out! Join us on a trip to taste the flavors of Tenochtitlan, and explore the endangered “floating islands” that fed the city—with a menu that included insect eggs, blue-green algae, and some adorable salamanders that just might hold the secret of eternal youth.
