History of Peppers
Chili peppers from Central America
There are two main kinds of pepper: black pepper and chili pepper. Chili peppers come from South America, and they're related to other South American plants like tomatoes, tobacco, and potatoes. Chili doesn't taste hot to birds, so possibly the hot taste evolved so that birds would eat the fruit and mammals wouldn't - birds do a better job of spreading chili pepper seeds.
But even if chili pepper plants didn't like people eating them, people liked to eat them anyway! People in South America were gathering this kind of pepper as early as 7500 BC, not long after people first came to South America. By about 4000 BC, farmers were growing chili peppers in South America.
Maya meal - tamales with chili sauce are under the table.
Chili peppers were one of the main foods of the Maya, along with corn, squash, and beans. Maya people often added chili peppers to tortillas or tamales to give them more flavor. They also mixed chili with chocolate and honey.
But our word chili is not from Maya but from the Nahuatl (Aztec) word "chilli". A very common Aztec meal was corn tortillas dipped in chili sauce. Aztec people also liked to mix tomatoes and avocados with chili to make salsa and guacamole.
