Here Brother Djoussou feasts on "cassava" which has been prepared outside of the MTC. It is not served in the MTC, but as you can see here, it has been prepared correctly and he is enjoying it. You are invited, as he would say.
Cassava is a major staple food in the developing world, providing a basic diet for over half a billion people. It is one of the most drought-tolerant crops, capable of growing on marginal soils. Nigeria is the world's largest producer of cassava, while Thailand is the largest exporter of dried cassava.
Cassava is classified as sweet or bitter. Farmers often prefer the bitter varieties because they deter pests, animals, and thieves. Like other roots and tubers, both bitter and sweet varieties of cassava contain antinutritional factors and toxins. It must be properly prepared before consumption. Improper preparation of cassava can leave enough residual cyanide to cause acute cyanide intoxication and goiters, and may even cause ataxia or partial paralysis. The more toxic varieties of cassava are a fall-back resource (a "food security crop") in times of famine in some places.
