Yuca (or manioc or cassava) in its processed form is called tapioca. Boiled, it is soft and sticky, with a buttery chewiness. Fried, it is sweet and crunchy. Since most are waxed to prevent drying, feel carefully for soft spots. To prepare, cut into desired lengths, then slit the "bark" and with a knife pull it off along with the pink underlayer. Keep uncovered at cool room temperature in an airy spot for a few days. Store at 45-50°F.
