Tejuino is a corn-based, fermented Mexican drink that dates from pre-Columbian times. It is made with corn flour (masa), water, piloncillo or panela (unrefined cane sugar), and sometimes lime juice. The ingredients are combined and left to ferment for several days.
It results in a slightly fizzy drink with low alcohol content, a sweet and sour flavor, and a thick texture. Because it is an ancient drink, it is hard to pinpoint where tejuino originated. It is believed to have first appeared among the Nahua people, native to Northwest and Central Mexico.
The drink was initially consumed during ceremonies and celebrations. It is now mostly available in Colima and the neighboring states of Jalisco and Michoacán. Depending on the region, tejuino is served with different accompaniments. In Jalisco, it is topped with lime sorbet (nieve de limón), while in Colima, it is poured over ice and comes drizzled with lime juice.
