Yam foo-foo (also called fufu, foufou, or foutou) is a staple food in Central and West Africa. It is a thick paste made from boiling starchy root vegetables, most notably yams. They are ground with a mortar and pestle until the desired consistency is reached.
Unsubstantiated claims have been made that the traditional method of eating fufu is to take a moderately-sized ball in one hand and indent it so that soup or other liquid substances can be imbibed from it. Chewing fufu is generally frowned upon.
