Imikembe is a Burundian household food of cassava roots that are peeled, boiled and broken up to remove the fibres, then left to ferment under water for about a week, with the water changed every two days. The sour cassava is eaten with beans and other legumes.

At a glance
Imikembe is a Burundian household food of cassava roots that are peeled, boiled and broken up to remove the fibres, then left to ferment under water for about a week, with the water changed every two days. The sour cassava is eaten with beans and other legumes. Made in 3 steps over 7 days. The longest step, ferment under water, changing the water every two days, takes 7 days (FermDB (Bokulich lab 2009).
Imikembe is boiled before it ferments, like ubuswage, but it is eaten after one week in water instead of two, and it is not boiled again or pounded into a ball.
Ubuswage (separate entry)Two-week soak, then re-boiled and pounded into a paste ball wrapped in plantain leaves.
Safety
Cassava holds compounds that release cyanide, and simple boiling does not reliably remove them [fao1990]. The Codex code of practice keeps direct cooking for low-cyanide sweet cassava, because these compounds survive heat [codex-rcp73]. No study we found measured cyanide in imikembe, so use only roots known to be low in cyanide. Bitterness is not necessarily a reliable guide to cyanide content [fao1990]. Do not cut the week under water short, and throw away the changed water.
