When you are busy thin slicing your fresh ginger you, you will quickly find out whether it is a good quality root or a fibrous and stringy dried out old log. A good quality fresh ginger root will be juicy when you slice it. It will slice easily - particularly across the grain it will slice easily. The grain will be tight or even hard to detect at all.
