Akamu

Ogi is a cereal pudding and popular street food from Nigeria, typically made from maize, sorghum, or millet. Traditionally, the grains are soaked in water for up to three days, before wet-milling or grinding and sieving to remove husks. The filtered cereal is then poured into a cheese clothe to get rid of water used in sieving and can be stored in it or in a fridge. It is then boiled into a pap, or cooked to make a creamy pudding also known as Agidi or Eko. It may be eaten with moin moin, acarajé or bread depending on individual choice. In Kenya, the porridge is known as uji (not to be confused with ugali) and is generally made with millet and sorghum. It is commonly served for breakfast and dinner, but often has a thinner gravy-like consistency. The fermentation of ogi is performed by various lactic acid bacteria including Lactobacillus spp and various yeasts including Saccharomyces and Candida spp.
