Last year I presented a Double Tendrils about the popular and seemingly ubiquitous snack of popcorn. Quite simply, it’s not just for watching movies. And around this time of year, we start eating more. Not only that, but it turns out to be a uniquely American contribution to the world’s cuisine.

The topic simply overflowed so much that we didn’t have room for tidbits about its deep history.

So here goes with ten related factoids that pop up on that front.

1. Try to think of a more purely American food than popcorn. Whether salted or buttered at a movie theatre, or as kettle corn at a county fair or a caramel popcorn ball come the holidays, we hoover it up, even when we’re not watching movies, OK?
2. Look, archeologists have found traces of popcorn in 1,000-year-old Peruvian tombs. But it goes back way even earlier.
3. The first use of wild and then cultivated corn points for now to the Bat Cave of west central New Mexico in 1948. Ranging from smaller than a penny to about two inches, those ears are about 5,600 years old, older than Adam and Eve, for anyone counting.
4. In tombs on the east coast of Peru, researchers have found grains of popcorn perhaps 1,000 years old. These grains have been so well-preserved that they will still pop.
5. Popcorn was integral to early 16th century Aztec ceremonies. As Bernardino de Sahagun observed, “And also a number of young women danced, having so vowed, a popcorn dance. As thick as tassels of maize were their popcorn garlands. And these they placed upon (the girls’) heads.” In 1519, Cortes got his first sight of popcorn when he invaded Mexico and came into contact with the Aztecs. Popcorn was an important food for the Aztec natives, who also used popcorn as decoration for ceremonial headdresses, necklaces and ornaments on statues of their gods, including Tlaloc, the god of rain and fertility.
6. An early Spanish account of a ceremony honoring the Aztec gods who watched over fishermen reads: “They scattered before him parched corn, called momochitl, a kind of corn which bursts when parched and discloses its contents and makes itself look like a very white flower; they said these were hailstones given to the god of water.”
7. Writing of Peruvian natives in 1650, the Spaniard Cobo said, “They toast a certain kind of corn until it bursts. They call it pisancalla, and they use it as a confection.”
8. Kernels of popcorn found in burial grounds in the coastal deserts of north Chile were so well preserved they would still pop even though they were 1,000 years old. Likewise, in southwestern Utah, a 1,000-year-old popped kernel of popcorn was found in a dry cave inhabited by predecessors of the Pueblos.
9. Indigenous Iroquois people in North America were documented popping corn kernels in heated pottery jars near the Great Lakes region in the 1600s.
10. The first patent for a microwave popcorn bag was issued to General Mills in 1981, and home popcorn consumption increased by tens of thousands of pounds in the years following.
