Soak your millet over night. Wash properly. Drain, add enough water to cover it. Set aside for grinding.

Pound your sweet potato, ginger and cloves together in a mortar. Put in a separate bowl, add little water.. then take to a grinding engine and grind. Grind the millet separately from the potato and ginger mixture. Grind until a smooth paste is formed.

Boil water in a big pot until steaming hot. Mix the millet paste in a big bowl, by adding little water to it (like you want to make your pap) mix throughly to avoid lumps. Pour the hot water and immediately start stirring it with a wooden spatula. Stir until it becomes thick like pap. Allow to cool down, then add the potato mixture and stir again.

At it point, it's no longer thick like the first time you poured the hot water. You can now seive using a filter cloth. After seiving, you can now add sugar or natural sweetener to taste. Pack in plastic containers and refrigerate.
