To Grate Ginger, Freeze It
When shopping for ginger at the store, please keep it in an airtight bag or container and put it in the freezer. Grating a whole piece directly off of the root is far more complex than grating it after purchasing it from the market.
Moreover, the peel will come out so finely grated that there’s no need for peeling beforehand. This method also keeps things fresh longer and helps preserve their freshness which can last up to six months when frozen.
