Great question.

If your dark enough you may just be able to pass as Mexican. I’m half Chinese and that seems to be good enough for a lot of people to guess that I’m Mexican.

If your white white you may need some extra steps for True Authenticity ™. You should probably buy whole corn kernels directly from a fair trade farm in Yucatan and hand grind it in a traditional mortar and pestel. If you don’t get blisters, it won’t taste right.
