Virado arose spontaneously during the early colonial period of Brazil as a dish of the bandeirantes. The bandeirantes traveled to the interior of Brazil to capture and enslave native Brazilians at first, and later to find gold, silver, and diamonds. They carried beans, pork, and corn flour in their backpacks to the interior of the state. Stored in the backpack, the ingredients "turned" (Portuguese: virar) and mixed, hence the name of the dish, "virado". Virado in the period of the bandeirantes consisted only of beans, usually cooked without salt so as not to harden them, maize flour, dried meat, and bacon. Cassava flour was substituted for corn flour after the introduction of the crop to the São Paulo region in the 18th century. The bandeirantes and other early settlers ate virado cold or warmed.[1][2]
The earliest written reference to virado is in 1602, when Nicolau Barreto made an expedition to present-day Paraguay, Bolivia, and Peru. It is also associated with the monção, expeditions by river to resupply remote areas of the Brazilian interior from the early 18th to the early 19th century.[3]
The dish became a staple of homes and farmsteads in the São Paulo region. Homes in São Paulo in the early colonial period were basic and lacked the elegance of those in Bahia, Pernambuco, or Rio de Janeiro. Virado was served at all times of the day with little variation; in this period it consisted of beans, bacon, flour, a piece of pork, smoked linguiça, and kale.
Rice was introduced to virado in the 19th century after the wide-scale introduction of the crop in Brazil; it was cooked in the remains of cooked pork or sausage, and additionally flavored with lard, garlic, and salt. Dessert served with virado consisted of fresh fruit such as oranges; bananas fried with cinnamon and sugar were also common.[4][2]
Dom Pedro I ate virado on August 17, 1822, at Fazenda Pau d'Alho, in São José do Barreiro, Vale do Paraíba on the trip from Rio de Janeiro to São Paulo.[4]
