What is "banku"

Banku is a Ghanaian dish which is cooked by a proportionate mixture of fermented corn and cassava dough in hot water into a smooth, whitish consistent paste. Served with soup, stew or a pepper sauce with fish. It is mostly preferred by the people of the Southern Regions of Ghana particularly the Ga tribe but also eaten across the other regions in Ghana. Banku is found throughout Ghana, and is one of the staple foods enjoyed by all tribes in the country.
