In a large pot, bring half of the water (about 2 quarts or 1.9 liters) to a boil.
Gradually add the maize meal to the boiling water, stirring constantly to prevent lumps.
Reduce the heat and continue to cook the maize meal mixture, stirring occasionally, until it forms a thick porridge. This should take about 10-15 minutes.
Remove from heat and let the maize meal porridge cool to room temperature.
If using dried munkoyo roots, soak them in the remaining water (2 quarts or 1.9 liters) for several hours or overnight to soften.
If using munkoyo root powder, dissolve it directly into the remaining water.
Once the maize meal porridge has cooled, mix it with the munkoyo-infused water.
Stir well to combine.
Transfer the mixture to a large container or a traditional clay pot.
Cover the container with a clean cloth and let it sit at room temperature for 2-3 days to ferment. The longer it ferments, the stronger the flavor will be.
After the fermentation period, strain the munkoyo beverage through a fine mesh strainer or cheesecloth to remove any solids.
If desired, add sugar to taste and stir well to dissolve.
Enjoy your meal!
