Brazilian cheese bread (Pao de Queijo) originated from African slaves who worked in the mining industry in Brazil. Common flour in that region was a rarity (and a luxury), so the local population began to work with cassava root. However, the product obtained from it is something between flour and starch (and closer to the second). There was no cheese then either, they did without it. But over time, life has improved, the number of products has increased and now Pao de Queijo is the business card of Brazil.
