Fufu is a staple side dish made by pounding cassava and unripe plantains together with a big wooden pole and mashing them while adding water. As it needs to be vigorously stirred, it usually takes two people to make it - one pounding it, and the other moving it around between the pounding.
Once the mixture is smooth, it gets shaped into small balls that are then placed in a stew or soup with meat. Similar to the Tanzanian ugali, an indentation is made in the ball, used for scooping up the sauce, with fufu acting as a spoon.
The texture is quite gummy and stretchy, while the flavor is bland, but dipping it into a stew gives fufu a spicy flavor that is slightly reminiscent of peanuts. Just make sure not to eat with your left hand, as this is considered extremely disrespectful in many parts of Africa, because the left hand is used for toilet-related actions.
