Nixtamalising corn requires soaking the kernels in an alkaline solution, usually made with lime water, before hulling and grinding them for cooking.

Researchers ruled out the possibility that the pits could have been used to collect and distribute water, since they were separated from the site's complex rainwater gathering system.
