Cassava. Cassava, manioc, or yuca (Manihot esculenta) is a staple source of starch in tropical countries. It contains the toxin linamarin which is metabolized to cyanide by enzymes in our gut. Cassava is the source of tapioca. In Brazil and other parts of South America they prepare farinha from it. The process of preparing these staples is long and requires the squeezing of the toxic liquid from the grated root. Boiling destroys the toxin. This liquid can be make it safe, by boiling it for two hours or more. Local food connoisseurs then use the detoxified liquor to prepare many dishes of their local cuisine. Perhaps the best known of these is Patos do cupi, i.e. duck cooked in this detoxified broth.
