Peel the yams and cut them into chunks. Rinse the yam pieces under cold water.
In a large pot, add the yam chunks and enough water to cover them.
Bring the water to a boil over medium-high heat. Reduce the heat to medium and cook the yams for about 20-25 minutes, or until they are tender and easily pierced with a fork.
Drain the cooked yams and transfer them to a large mixing bowl or mortar and pestle.
While still hot, pound or mash the yams until they become smooth and stretchy. This can be done using a potato masher, a large wooden spoon, or a mortar and pestle for a more traditional method.
If the mixture is too thick, you can add a little hot water to achieve the desired consistency.
Add salt to taste and mix well.
For added flavor, you can mix in 1-2 tablespoons of butter or palm oil.
Shape the pounded yam into small mounds or serve it as a large mound on a serving plate.
Enjoy your meal!
