esquites

The Nahuatl word ízquitl referred to corn kernels toasted dry in a clay pot, a technique the Mexica and earlier Mesoamerican cultures used long before the Spanish arrived in 1519. The root verb izca meant to toast without oil. Aztec markets in Tenochtitlan sold ízquitl as a portable, shelf-stable food, much as modern cities sell roasted nuts.

After the conquest, Spanish settlers transcribed Nahuatl sounds imperfectly. The initial vowel cluster shifted over the colonial period, and ízquitl became esquite in spoken Mexican Spanish. The plural esquites then attached to the street dish: toasted corn kernels simmered in water with epazote (the herb Dysphania ambrosioides), chile, and salt, served in cups with lime juice and chili powder.

The modern preparation diverges from the pre-Columbian original in important ways. Post-conquest esquites often include mayonnaise, Cotija cheese, and Valentina hot sauce, ingredients that arrived from Spain or were invented in 20th-century Mexican kitchens. Vendors in Mexico City sell the cup version while Oaxacan markets sell a drier, more herb-forward variation. Both trace back to the same toasted kernel.

Corn itself, Zea mays, was domesticated from the wild grass teocintle in the Balsas River valley of Mexico around 9,000 years ago. The word maíz that entered Spanish and then English came from Taíno, not Nahuatl. But the preparation technique in esquites is Nahuatl in origin, a dry-toast method that predates every other corn dish in the colonial record.
