Ginger root. Tips for storing freezing fresh ginger root
If you like to use fresh ginger, take the ginger root when you bring it home from the store cut off what you need for the moment, and then wrap the rest in wax paper and then put in a sealed baggie and put it in the freezer. Every time you want a bit of fresh ginger just take it out and clip a little off and put the rest back.
You will find that the frozen ginger can be easily grated. Freezing stops all of those stringy and lumpy bits in whatever you are cooking, without compromising the flavour.
