Taro root is to poi, as a potato is to mashed potato (taste wise). That's a very rough comparison though. Texture-wise, try to imagine what it would be like to eat a tablespoon of Elmer's Glue (it'll take more than a few chews, if you even call it that, to get it down). It's really an acquired taste.
What does POI taste like?
