Sorghum and millet are kept in big storages made out of clay and prime-grass. Beans are mixed with ash and stored in clay pots. If the clay pots are not put on top of each other they can be sealed with clay. Also blanching and drying are used in preserving foodstuffs. Clay pots are ideal for storing water and pito.
Fish is preserved by smoking or drying.
Food itself is prepared either outside or inside on open fire. Thick smoke while preparing food can be irritating and dangerous for health. Charcoal or wood is used for fuel. Usually the fuel wood has to be fetched at a distance of several kilometres. Wood drifting along the river is also used.
