In a large pot, bring 4 cups of water to a boil. Add the salt to the boiling water.
Gradually add the maize flour to the boiling water, stirring constantly to prevent lumps from forming.
Reduce the heat to low and continue stirring the mixture. Cook for about 10-15 minutes, or until the xima thickens and starts to pull away from the sides of the pot.
If desired, stir in 2 tablespoons of vegetable oil for added richness and flavor.
Remove from heat and let it sit for a few minutes before serving.
Enjoy your meal!
