What is "piracui"

Piracuí is traditionally known in the Amazon region as "farinha de peixe" (fish flour) and is traditionally made from crushed or shredded dried salted fish. The most common fishes are acari and tamuatá, but piracuí can be made from other species of fish, such as bodó. It is eaten mixed with olive oil, onion and cassava flour.
