In a large pot, bring the water to a boil over medium heat.
In a separate bowl, mix 1/2 cup of maize flour with a small amount of cold water to make a smooth paste.
Once the water is boiling, slowly stir in the maize flour paste, stirring continuously to prevent lumps.
Gradually add the remaining maize flour, stirring constantly to ensure even mixing and to avoid lumps.
Reduce the heat to low. Continue to cook and stir the mixture for about 10-15 minutes. The nsima should become thick and smooth. If it’s too thick, you can add a bit more water.
Once cooked, remove from heat. Let it sit for a few minutes before serving.
Enjoy your meal!
