Unlike the meat-filled tamal beside it on the same cart, humita has no meat filling: fresh grated corn, onion and a piece of cheese do the work, and some cooks make a sweeter version with sugar.
Fresh corn ground into a sweet-savory paste with cheese, onion, and spices, wrapped in the corn's own husk (chala) and steamed. Sold alongside tamales at Salta's street stalls and markets, often from the same steaming pot.
