In a medium saucepan, bring the water to a boil over medium heat. Add the salt.
Gradually stir in the maize meal while continuously stirring to prevent lumps. Reduce the heat to low.
Cover the saucepan and let the pap simmer for about 10-15 minutes, stirring occasionally. The mixture should thicken and become smooth.
If using, stir in the butter until melted and fully incorporated.
For a creamier texture, add a bit of milk or cream if desired. Stir until well mixed.
Enjoy your meal!
