On Fufu (from a site with too many popups to link)
Fufu (Foo-foo, Foufou, Foutou, fu fu) is to Western and Central Africa cooking what mashed potatoes are to traditional European-American cooking. There are Fufu-like staples all over Sub-Saharan Africa: i.e., Eastern Africa's Ugali and Southern Africa's Sadza (which are usually made from ground corn (maize), though West Africans use maize to make Banku and Kenkey, and sometimes use maize to make Fufu). Fufu is a starchy accompaniment for stews or other dishes with sauce. To eat fufu: use your right hand to tear off a bite-sized piece of the fufu, shape it into a ball, make an indentation in it, and use it to scoop up the soup or stew or sauce, or whatever you're eating.
In Western Africa, Fufu is usually made from yams, sometimes combined with plantains. In Central Africa, Fufu is often made from cassava tubers, like Baton de Manioc. Other fufu-like foods, Liberia's dumboy for example, are made from cassava flour. Fufu can also be made from semolina, rice, or even instant potato flakes or Bisquick. All over Africa, making fufu involves boiling, pounding, and vigorous stirring until the fufu is thick and smooth.
I like the east African version (I think) far better.
