tejuino

Tejuino is a lightly fermented drink made from masa, the same corn dough used for tortillas and tamales. The word is Nahuatl in origin, from the western Nahuatl dialects spoken in what is now Jalisco and Nayarit before and during the Spanish colonial period. The root connects to Nahuatl terminology for corn-based preparations and fermented foodstuffs. The drink is distinct from pulque, which is agave-based, and from tepache, which ferments pineapple rinds, occupying its own category in the pre-Columbian taxonomy of fermented corn.

Fermentation of corn was standard practice among the indigenous peoples of western Mexico before 1521. The process made dense calories more digestible, produced a mild alcohol content that held ceremonial significance, and extended the useful life of ground corn in a hot climate. The Spanish colonial administration attempted to regulate and tax indigenous fermented drinks from the sixteenth century onward, but tejuino, consumed at a domestic and local market scale, largely stayed beneath the administrative gaze and survived intact.

By the nineteenth century, tejuino was a fixture of street commerce in Guadalajara and surrounding Jalisco towns. Vendors served it cold in clay cups with lime juice squeezed in, often with a scoop of lime sorbet floating on top, and sprinkled with chili salt. That configuration, sour and sweet and cold and hot at once, became the canonical tejuino experience and has not changed in the century since. The drink was poor food, which meant everyone ate it.

Today tejuino ranks alongside birria and tortas ahogadas as one of the foods Guadalajara considers definitionally its own. It is sold from plastic coolers and styrofoam cups, still finished with lime and chili salt in the same proportion as a hundred years ago. The Nahuatl word survived the colonial period, the independence period, and the twentieth century without modification: a syllable-by-syllable trace of the language that named the drink before the Spanish named anything at all.
