Oshikundu is meant to be drunk fresh: left too long it keeps fermenting, turning sourer and mildly alcoholic, so households brew it daily and roadside sellers offer it each morning.
Pearl millet (mahangu) flour and bran are mixed with malted sorghum and tepid water, left to ferment for a day, then strained into a tangy, lightly fizzy, porridge-thin drink served in a calabash or cup.
