In a large pot, bring 3 cups (750 ml) of water to a boil over medium-high heat.
Add the salt to the boiling water if using.

In a bowl, mix the remaining 1 cup (250 ml) of water with 1 cup (120 g) of the maize meal to make a smooth slurry.

Gradually pour the maize meal slurry into the boiling water, stirring continuously to prevent lumps from forming.
Reduce the heat to medium and continue to cook, stirring constantly, until the mixture thickens and begins to bubble.

Gradually add the remaining 1 cup (120 g) of maize meal to the pot, a little at a time, stirring constantly. The mixture will become very thick.
Continue to cook and stir for about 5-10 minutes, or until the sadza pulls away from the sides of the pot and is fully cooked.

Using a wooden spoon or a special sadza paddle, shape the sadza into small, round portions or mounds.
Serve the sadza hot with your favorite Zimbabwean dishes, such as nyama (stewed meat), muriwo unedovi (vegetables with peanut butter), or kapenta (fried dried fish).
Enjoy your meal!
