Domesticated plants of Mesoamerica, established by agricultural developments and practices over several thousand years of pre-Columbian history, include maize and capsicum. A list of Mesoamerican cultivars and staples:
Maize was domesticated in Western Mexico and Mesoamerican cultures expanded wherever it was cultivated. It became widespread in the Late Archaic Period and was grown wherever conditions allowed.
The early use of maize focused on the consumption of unripened kernels. Before people settled into villages and began farming, the amount of time it took to invest in maize was too great. The output of wild maize did not justify the time and work needed to grow the crop.
However, maize could be both dried and stored which was very important to early Mesoamericans as it could be used on a year-round basis. Drying meant that it could be transported as well. The common bean (Phaseolus vulgaris) was often grown with maize. These two plants provide complementary dietary amino acids. Improved bioavailability of maize was discovered using a special process involving limewater, which also added calcium.
Maize is also associated with festival and feast foods. Before it was domesticated and became a main crop, maize was used as a basis for beer. Beer was transported in decorated vessels and ceramic pottery. These vessels could be taken to social and ritual occasions.
Ritual events or festivals, such as ball games, feasts, and calendar turnings, involved the royal members who took part in the sacrifice of blood-letting and piercing as repayment to the gods for having given maize to the people that year.
Another example of how maize played such a large role in Mesoamerica, is when deities were portrayed with maize. Quetzalcoatl is connected as being a creator of humans in Mesoamerica. This deity is also seen as the one who took maize from the underworld and gave it to humans in the present world.
Capsicum is the generic name of the chili pepper plant, which is a native domesticated plant from Mesoamerica. Capsaicin reduces the bacterial load when something can not be refrigerated. In Mesoamerica, the capsaicin spice was also used to relieve joint pain, and as an intestinal stimulant, so capsicum is also known as a medicinal plant. The peppers from capsicum plants can be used in a fresh or dried state. A dried chile pepper is stronger and more effective than a fresh chile pepper.
