Roots and tubers from Cameroon
Mintoumba is a Cameroonian cake of fermented cassava paste mixed with red palm oil, a little salt and chilli, then cooked in a pot and dried. The cassava is soaked until soft and sour, pressed and ground before the oil goes in. It is eaten with a sauce or as a snack.

Mintoumba is a Cameroonian cake of fermented cassava paste mixed with red palm oil, a little salt and chilli, then cooked in a pot and dried. The cassava is soaked until soft and sour, pressed and ground before the oil goes in. It is eaten with a sauce or as a snack. Made in 4 steps over 3 days – 4 days. The longest step, soak the peeled roots until soft, takes 3–4 days (Tanyitiku M.N. 2024). Lactic acid bacteria, 3.10 log10 CFU/g in Yaoundé market mintoumba, lower than in products without palm oil does most of the fermenting.

Mintoumba is the only one of the Yaoundé cassava products with palm oil mixed into the fermented paste before steaming. Like garri toasted with palm oil, it had a low lactic acid bacteria count, which the study links to the palm oil.
Mintoumba is sold ready to eat. Yaoundé market samples carried coagulase-positive staphylococci (5.66 log10 CFU/g), E. coli and coliforms. The author says E. coli and coliforms suggest poor cleanliness in handling and improper storage. Cassava also holds compounds that release cyanide, most of them in the peel [codex-rcp73] [fao1990]. FAO says prolonged soaking lets the cyanide dissolve out, squeezing is a fundamental step in removing it, and simple boiling of fresh root is not always reliable [fao1990]. The Yaoundé study did not measure cyanide and no source we read measures it in mintoumba, so do not shorten the soak or skip the pressing, and do not assume they remove all of it.

Afrik.com published an interview on 8 February 2022 with a seller at the Saker market in Deïdo, Douala, who described mintoumba as a traditional Cameroonian cake of fermented cassava and red palm oil. Tanyitiku sampled it at six Yaoundé markets between November 2022 and April 2023. A second Afrik.com article, published on 24 July 2024, calls it a cake of the forest regions of Cameroon, often present at weddings, births and community feasts, and says the red palm oil gives it its colour and flavour [afrik2024].
