In a large pot, bring 3 cups of water to a boil. Add the salt and stir to dissolve.
In a separate bowl, mix the cassava flour with the remaining 1 cup of cold water to form a smooth paste. This helps prevent lumps when adding it to the boiling water.
Gradually add the cassava paste to the boiling water, stirring constantly with a wooden spoon or whisk to avoid lumps.
Continue to stir vigorously as the mixture thickens and becomes smooth. Reduce the heat to low and cook for about 15-20 minutes, stirring frequently to prevent sticking.
The funge should have a thick, smooth, and slightly stretchy consistency. If it is too thick, you can add a little more hot water and stir until you reach the desired consistency.
Remove the funge from the heat and let it cool slightly. Wet your hands with water and shape the funge into small balls or mounds.
Enjoy your meal!
