You need to marvel how individuals initially discovered how you can eat some meals which are beloved right this moment. The cassava plant is toxic if not rigorously processed via a number of steps. Yogurt is principally outdated milk that’s been round for some time and contaminated with bacteria. And who found that popcorn might be a toasty, tasty deal with?
These sorts of meals mysteries are fairly laborious to unravel. Archaeology is dependent upon strong stays to determine what occurred prior to now, particularly for individuals who did not use any type of writing. Sadly, most stuff individuals historically used produced from wooden, animal supplies or material decays pretty quickly, and archaeologists like me by no means discover it.
We have now a number of proof of laborious stuff, corresponding to pottery and stone instruments, however softer issues — corresponding to leftovers from a meal — are a lot more durable to seek out. Typically we get fortunate, if softer stuff is present in very dry places that preserve it. Additionally, if stuff will get burned, it could final a really very long time.

Corn’s ancestors
Fortunately, corn — additionally referred to as maize — has some laborious elements, such because the kernel shell. They’re the bits on the backside of the popcorn bowl that get caught in your enamel. And since it’s important to warmth maize to make it edible, generally it received burned, and archaeologists discover proof that method. Most fascinating of all, some vegetation, together with maize, include tiny, rock-like fragments called phytoliths that may final for hundreds of years.
Scientists are fairly positive they understand how outdated maize is. We all know maize was in all probability first farmed by Native Americans in what’s now Mexico. Early farmers there domesticated maize from a kind of grass called teosinte.
Earlier than farming, individuals would collect wild teosinte and eat the seeds, which contained quite a lot of starch, a carbohydrate such as you’d discover in bread or pasta. They might choose teosinte with the biggest seeds and ultimately began weeding and planting it. Over time, the wild plant developed into one thing like what we name maize right this moment. You’ll be able to inform maize from teosinte by its bigger kernels.

There’s proof of maize farming from dry caves in Mexico as early as 9,000 years ago. From there, maize farming unfold all through North and South America.
Popped corn, preserved meals
Determining when individuals began making popcorn is more durable. There are a number of kinds of maize, most of which will pop if heated, however one selection, really referred to as “popcorn,” makes the very best popcorn. Scientists have found phytoliths from Peru, in addition to burned kernels, of such a “poppable” maize from as early as 6,700 years in the past.
You’ll be able to think about that popping maize kernels was first found accidentally. Some maize in all probability fell right into a cooking hearth, and whoever was close by discovered that this was a useful new method of making ready the meals. Popped maize would final a very long time and was straightforward to make.
Historical popcorn was in all probability not very like the snack you would possibly munch on the movie show right this moment. There was in all probability no salt and undoubtedly no butter, since there have been no cows to milk in the Americas yet. It in all probability wasn’t served sizzling and was probably fairly chewy in contrast with the model you are used to right this moment.
It is unimaginable to know precisely why or how popcorn was invented, however I might guess it was a intelligent approach to protect the edible starch in corn by eliminating the little little bit of water inside every kernel that might make it extra vulnerable to spoiling. It is the heated water within the kernel escaping as steam that makes popcorn pop. The popped corn might then final a very long time. What you might take into account a tasty snack right this moment in all probability began as a helpful method of preserving and storing meals.
