Popcorn

Zea mays

In Native American lore, maize (or corn as it is commonly called in the U.S.) was one of the "three sisters." Corn seed, along with beans and squash, were planted and grown together, supporting each other in their life cycle and providing a very balanced diet of carbohydrates, proteins and vegetable fats to their cultivators.

Popcorn is one of the oldest forms of cultivated corn. Based on the physical shape of their kernels, popcorn can be generally classified into two types; pearl or rice. Popcorn usually has small kernels that contain a high percentage of horny starch^[1]; even more than flint-types. This causes them to violently burst and expand upon heating.
