This vivid purple yam is a tuber plant has a rough and dark colored
exterior and a purple interior. It’s requires proper cooking (like most
wild yams) to detoxify the plant and make it edible, but other than
that macabre bit of information, it tastes really good – fibrous and
starchy texture, with a slightly sweet aftertaste.
I’m told that people used to eat this to supplement their diet during the famine but personally, it tastes alright to me. :)
