Sieve the corn & cassava flour separately. Place a pot on the fire add water & bring to a boil.

Add water to the corn flour & stir to get a slightly thick consistency. Pour into the boiling water while stirring. Cover & allow to cook on low heat for 10mins.

Add the cassava flour in two batches. Stir until it reaches the thickness you want. If too thick, add more hot/ cold water. Make holes with the stirring stick add water so the water gets to the bottom. Cook it on low heat for 20mins.

It should look like this. You will notice its slightly elastic as you stir. Take off the heat & wrap in cellophane.

Note that the more cassava flour you add, the more elastic & soft the swallow will be.
