Directions

Peel, wash, and cook the cassava until it is tender.
Still warm, mash it, add the sugar and boiled water, then mix thoroughly until you have a thick paste.
Place the dough in a clay pot and let it ferment for 5 to 10 days for a better rise.
On the day of the tasting, mix the dough with water, then pass it through a sieve. ≈ 4 min
Serve, and if you like, sprinkle with cinnamon. ≈ 2 min
In the traditional Peruvian Amazonian method, the cassava is chewed and then spat out into a container of water, where it rests: the enzymes in saliva convert the starch into sugar, and the liquid ferments.
This method is not recommended due to hygiene concerns. ≈ 3 min
