This is Ghana's national dish. The fufu itself is made of boiled and pounded starches - either plantain and cassava or yam. There are three main soups that it can be submersed in - groundnut (yes, peanut soup!), light soup (a pepper and tomato broth) or palm nut soup (made from the pulp of palm kernels). There is a real art to eating fufu and most "obrunis" are hopeless at it. The object is to plunge your hand into the hot soup, pull of a bit size piece of the fufu, manipulate it to crate a little well where a bit of soup can sit, and plop the whole thing in your mouth and swallow. No chewing!
I ran into a display of FUFU flour at the Buford Farmers Market this morning; I love all things plantain, I will try FUFU for sure. The term "obruni" in the description above refers to caucasians.
