A friend gave us a bag of these. Covered in dirt and mud, but that's how things are grown right? All great and fresh, except I have no clue what these are. Tubers, but what? Looks exactly like ginger root. Pure white flesh, incredibly crispy, not much in way of flavour. Sort of a very subtle earthiness, quite similar to ginseng in fact.
For some reason, I'm thinking Jerusalem artichoke. I don't know why - it's not like I've ever seen one, or tasted one. Can someone confirm/correct me? And let me know how these are eaten?
