Pão de queijo (“Cheese Bread” in Portuguese) is a small, baked, cheese-flavored roll, a popular snack and breakfast food in Brazil. Its origin is uncertain; it is speculated that the recipe has existed since the eighteenth century in the Brazilian state of Minas Gerais, but it became popular throughout the country after the 1950s. It is also widely eaten in northern Argentina. It is inexpensive and often sold from streetside stands by vendors carrying a heat-preserving container. In Brazil, it is also very commonly found in groceries, supermarkets and bakeries, industrialized or freshly made.
