Pão de Queijo
Minas Gerais, Brazil (Afro-Brazilian mining community tradition, 18th century)
Pão de queijo — Brazilian cheese bread — is one of the world's most texturally distinct bread preparations: small, round rolls made from cassava starch (polvilho azedo, the sour-fermented version) with eggs, oil, salt, and grated queijo Minas curado (aged Minas cheese), baked until the exterior is golden and slightly crisp while the interior remains extraordinarily chewy, elastic, and almost hollow — the unique property of gelatinised tapioca starch baked with cheese. The fermented cassava starch (polvilho azedo) provides a slightly sour, yeasty note that distinguishes professional pão de queijo from versions made with sweet polvilho. The texture is the entire point: the elastic, stretchy, cheese-flavoured interior has no parallel in wheat bread.
