Pão de queijo

Pão de queijo or Brazilian cheese balls is a small, baked cheese roll or cheese ball, a popular snack and breakfast food in Brazil. It is a traditional Brazilian recipe, originating in the state of Minas Gerais. In Brazil, it is inexpensive and often sold from streetside stands by vendors carrying a heat-preserving container. It is also commonly found in groceries, supermarkets and bakeries, industrialized or freshly made. The cassava flour is what gives the snack its distinct texture, which is chewy and elastic, being crunchy on the outside. Most countries in South America have their own versions of this snack; the main difference between them in general is the ingredients used in the recipe, which can change slightly giving different results. In Brazil traditionally both sour and sweet cassava flour are used; the Brazilian recipe also excludes some ingredients used in other countries such as corn starch, all-purpose flour, black pepper, sugar, fennel, and baker's yeast.
