tlayuda

A tlayuda is a large, partially dried tortilla from Oaxaca, typically thirty centimeters across, griddled until it blisters and stiffens, then spread with black bean paste, asiento (unrefined lard), quesillo, and whatever the cook has on hand. The word appears in Oaxacan Spanish by at least the nineteenth century, and its structure points toward a Nahuatl origin. The most plausible reconstruction links it to tlayo, a Nahuatl term for a thick tortilla-like preparation, combined with a locative or adjectival suffix current in the Oaxacan Nahuatl of the colonial period.

Oaxaca has its own corn varieties, notably bolita, a round kernel that produces a softer, more extensible masa than the elongated corns of central Mexico. The large format of the tlayuda suited bolita dough: the masa could be pressed thin and wide without tearing. Zapotec and Mixtec communities in the valleys around Oaxaca City were making large-format tortillas long before the word tlayuda appeared in written records, and the Nahuatl name arrived through trade contact rather than conquest.

The partial drying that defines the tlayuda was practical. A tortilla allowed to go slightly stiff on one side could be carried in a cloth without sticking, eaten hours later without molding, and loaded with heavy toppings without collapsing. Farm laborers and market traders in the Central Valleys relied on it as a portable meal. By the mid-twentieth century it had moved from field food to evening food, the base for a full spread at family tables in Oaxaca City.

Outside Oaxaca, the tlayuda gained a wider audience in the early 1990s as Oaxacan cooking drew attention from food writers and chefs in Mexico City and the United States. Rick Bayless described it in print around that time, and a comparison to pizza lodged in the American food press, which helped it migrate into restaurant menus far from its origin. The word entered English food writing as a borrowing from Mexican Spanish and now appears in several major English-language dictionaries.
