A Two-Stage Fermentation of Cassava

Abstract

ONE of the staple foods of the people of the rain forest belt of West Africa is gari, a starchy food prepared from the root of the cassava plant (Manihot utilissima). The traditional preparation of gari1 consists briefly of the following stages: both the corky outer peal and the thick cortex are removed; the body of the root is grated by hand on home-made raspers; the greater part of the juice is removed from the pulp by primitive pressing; the pulp is left in bags for 72–96 hr. before it is fried. During this time fermentation occurs; hand-made raffia fabrics are used for ‘sifting’. A certain amount of fibre and ungrated ends of the roots are removed here. The pulp is afterwards heated in large iron pans over an open fire with or without the addition of palm oil.
