I prefer Ginger root for stir fries. I store my ginger root in a zipper bag in my freezer. When I want the ginger I just remove the end skin and grate the frozen root over the pot.
It goes through the fine grater and sprinkles over the surface. No clumping. I return ginger in bag to the freezer.
This keeps well. I use it in Ginger tea and ginger cookies. I use it often and there is much less waste. I like big round roots . Easier to handle.
