A couple of weeks ago, I bought a namé root. Within a few days, it rotted. So, I went back to the store and asked for another one. The second one was not rotten, but it was dark brown inside. I roasted it, but it stayed hard. Then I boiled it some, but it tasted like cardboard. Isn't namé supposed to be light-colored inside? Was my namé just extremely old? Just wondering. I plan to throw out what's left, since I don't particularly like to eat cardboard.
