Tucupi is a traditional ingredient commonly used in the cuisine of the Amazon region, particularly in the state of Pará.
It is a yellowish-brown sauce made from the juice extracted from manioc root (also known as cassava or yuca). The preparation of tucupi involves a fermentation process to remove the naturally occurring cyanide compounds found in raw manioc. The root is peeled, grated, and soaked in water for several days, allowing it to ferment.
The sauce is also used in other traditional Amazonian recipes, including fish stews, grilled meats, and sauces for rice or noodles. It's important to note that raw manioc contains toxic compounds, and consuming it without proper preparation can be harmful.
