Add 2 cups of cold water into a pan with a long handle. Pour ⅔ of the corn meal into the pan and mix well with a wooden spoon.
Place on medium heat and stir continuously with a wooden turner/turning stick until the mixture starts to boil with bubbles as it becomes thicker. Cover the pan for a few minutes to allow the maize meal to cook.
Reduce the heat to very low, then add the remaining cornmeal into the pan. Mix the flour into liquid by stirring vigorously and pressing against the sides of the pot to get rid of lumps. Stir and press until the mixture becomes a firm paste with a smooth consistency.
Add a little water to the pan and cover to allow the sadza to cook properly. After about 5 mins, stir again to mix in the water and continue to do this until there is no raw flour taste and the paste is smooth.
