Peel the plantains or yams and cut them into chunks.
Place the chunks in a large pot and cover with water.
Bring to a boil over medium-high heat. Reduce the heat and simmer until the plantains or yams are tender (about 20-30 minutes).
Drain the plantains or yams and return them to the pot or a large mixing bowl.
Mash with a potato masher or fork until smooth. You can add a little water if needed to achieve a smooth consistency.
Traditionally, fufu is pounded using a mortar and pestle, but you can use a sturdy spoon or a stand mixer if you prefer.
Continue to pound or stir the mixture until it becomes smooth and elastic.
Shape the fufu into balls or serve it as a soft, smooth mound.
Fufu is typically served as a side dish with soups, stews, or meat dishes.
Enjoy your meal!
