Cozumel has a culture that predates the piers by about two thousand years, and it is not on display in a lobby. It lives in kitchens, in a village chapel, and in a few families who still do things the long way.
You start with masa. Nixtamalized corn, a wooden press, a comal over wood fire, and a woman from the island who will tell you kindly that your first three tortillas are terrible. By the fifth one they puff. Then cacao: beans toasted, husked and ground on a metate, mixed with water and a little chile the way it was drunk here long before anyone added sugar and milk.
In between there is a copal blessing — not a performance, just the way a house is cleared and a guest is welcomed — and the story of El Cedral, the oldest settlement on the island, where the May festival still mixes a Catholic mass with a pig's head, ribbons and a dance that has been going since 1848. Your guide will explain the parts that look strange and why they are not.
You eat what you made. You leave knowing something about this place that does not fit on a postcard.
