Use a microplane grater for shaving ginger
The microplane grater is your greatest buddy when cooking with ginger, and it's one of Ina Garten's favorite kitchen equipment. Ginger, citrus fruits, and garlic are all easily shredded with the microplane grater. According to Bake Starters, a microplane is easier to use in the kitchen for fine grating since the size of the blades results in a smoother grate than a box grater or a knife.
You'll also note that a microplane grater produces more consistent results and is much simpler to clean than a box grater. Furthermore, unlike a box grater, a microplane grater allows you to grate in both directions. When shredding ginger, utilize just the firmest sections of the root. If it's a little soft, place it in the freezer for a few minutes before grating.
