Is there some great (no pun intended) gadget that grates ginger. My microplaner practically juices it. The small-holed side of my box grater doesn't work at all. I can use the large-holed side, but nothing really works. Is there something out there I don't know about (or some trick that will make my microplaner efficient)? Do microplaners wear out? Maybe I just need to get a newer, sharper instrument?
