Disambiguation

'Sweet potato' and 'yam' are often used interchangeably, though they are distinct vegetables. Yams are more cylindrical in shape with a brown, rough, bark-like skin that is difficult to peel. Yams tend to be less sweet and much drier than sweet potatoes.

Description

Yams vary in size from that of a small potato up to 5 feet in length. The flesh color varies from white, purple, yellow and pink.
