Directions

  1. Peel, wash, and cook the cassava until it is tender.
  2. Still warm, mash it, add the sugar and boiled water, then mix thoroughly until you have a thick paste.
  3. Place the dough in a clay pot and let it ferment for 5 to 10 days for a better rise.
  4. On the day of the tasting, mix the dough with water, then pass it through a sieve. ≈ 4 min
  5. Serve, and if you like, sprinkle with cinnamon. ≈ 2 min
  6. 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.
  7. This method is not recommended due to hygiene concerns. ≈ 3 min
