Cassabe is a type of bread prepared from cassava. It is common to South America. Similar products are made in other cassava-growing regions. It is the staple diet of the Amazonian Indians. There are two different methods for making cassabe, depending upon whether the roots are soaked and fermented or if they are just peeled and grated. The variety of cassava and the level of cyanide containing compounds within the tuber will determine whether fermentation is required.
