A deep-fried ball with cheese inside, made of yuca flour (1 medium). It has various forms through South America and in Colombia it is often called Bunuelo. Yuca (not Yucca) is a root crop. Yuca is Manihot esculenta, and in some countries, it is called cassava, manioc, macaxeira, mandioca or aipim - a woody shrub native to South America of the spurge family, Euphorbiaceae. Although a perennial plant, cassava is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root. Cassava is the third-largest source of food carbohydrates in the tropics, after rice and maize, providing a basic diet for nearly one billion people. It is one of the most drought-tolerant crops, and so, is grown in the Northern Territory of Australia.
