Taro is a root vegetable that grows in tropical and subtropical regions and has been a staple in cultures from Africa to Hawaii more or less forever. Recently, taro has become popular in more temperate countries, including the United States in a number of different forms, including as an alternative to potato chips.
Taro chips are a creamy-white color with little, wavy purple lines, almost as though purple thread had been mixed into the flesh somehow. The flavor and texture is similar to that of potato, but just different enough to be interesting, and the purple lines add visual appeal.
