Cazabe: the Taíno bread of a poisonous root, and the press a Spanish official wrote down in 1535

Bitter cassava kills unless its juice is pressed out and the pulp heated. Oviedo set down the whole Taíno sequence - the grater, the woven çibucan press, the clay burén - along with the market price of a carga in Santo Domingo, the year the bread keeps at sea, and the remark that few Indians still knew the trick because the old ones were dead. Modern neurology confirms what the process is for.
