In a large mixing bowl, combine the cassava flour and salt.
Gradually add the warm water to the cassava flour, mixing continuously until a smooth dough forms. The dough should be firm but pliable. Add more water if needed.
Divide the dough into small portions and shape each portion into a small ball or oval shape, about 1-2 inches in diameter.
Use your hands to smooth out any cracks in the dough balls.
Fill a large pot with water and bring it to a boil.
Lightly grease a steaming basket or a steamer insert with vegetable oil to prevent the dumplings from sticking.
Place the shaped dumplings in the steaming basket, making sure they do not touch each other.
Place the steaming basket over the boiling water, cover, and steam for about 15-20 minutes, or until the dumplings are firm and cooked through.
Remove the dumplings from the steamer and let them cool slightly before serving.
Enjoy your meal!
