In Argentina, humitas are prepared with fresh corn, sautéed onions, pumpkin, tomato and some spices, depending on the region or taste. The dough is wrapped in corn husks and boiled or it is cooked in a big pan and served in bowls. It is also common to add some diced cheese to the dough, typically queso fresco. They can be found in restaurants and markets in Tucuman and other provinces of the north of Argentina
In Chile
Humitas in Chile are prepared with fresh corn, onion, basil, and butter or lard. They are wrapped in corn husks and baked or boiled. They may contain ají verde. The humitas are kept together cooking with thread or twine. They can be made savory, sweet, or sweet and sour, served with added sugar, chile pepper, salt, tomato, olive and paprika etc. In Chile, humitas are traceable back to the 19th century.
In Ecuador
As in Chile, Ecuadorian humitas are prepared with fresh ground corn with onions, eggs and spices that vary from region to region, and also by each family's tradition. The dough is wrapped in a corn husk, but is steamed rather than baked or boiled. Ecuadorian humitas may also contain cheese. This dish is so traditional in Ecuador that they have developed special pots just for cooking humitas. Ecuadorian humitas can be salty or sweet.
In Peru and Bolivia
In the central Andes region, humitas are prepared with fresh corn combined with lard and salt and queso fresco for a savory dish or with fresh corn with lard, sugar, cinnamon and raisins for a sweet dish. Savory humitas may also be prepared with anise.These are typically very rare in other parts of South America. These humitas are prepared with corn wrapped in corn husks and can be cooked in boiling water, placed in a pachamanca oven, or steamed. They can be wrapped in several ways. One of the earliest references to huminta in Peru was written by the Inca Garcilaso de la Vega in his Comentarios Reales del Inca, which he published in Lisbon in 1609. In talking about huminta he describes his own memories of consumption about the time he lived in Peru between 1539 and 1560. From this it can be deduced that huminta was already prepared in Peru during this time.
