With its indigenous influences, Amazonian fare is Brazil’s most unique cuisine. Street vendors in many cities sell tacacá, a spicy soup made with tapioca, dried shrimp and tucupí sauce (extracted from manioc). Ask a local to suggest a clean and reliable kiosk and try it. Regional fish, like tambaquí and pirarucu, are prepared in several ways. Another specialty is a duck stew called “pato no tucupi.” The pirarucu, nicknamed the codfish of the Amazon, is good as a grilled fillet.
