I had been using powdered ginger for years.
Then I discovered whole dried ginger. The dried ginger stored well and when finely grated, gave off a wonderful aroma.
Then I discovered fresh ginger root. There is nothing that can compete with the smell and taste of fresh ginger root. Unfortunately, it does not last long in the fridge.
If you go through fresh ginger root quickly, the best way to store it is in a paper bag in the vegetable crisper drawer in your fridge.
If you are like me, using ginger occasionally, the best way is to peel the ginger root and then freeze it.
When I want fresh ginger, I just pull it out of the freezer, use my microplane grater and grate away...
Try it. You'll never go back to the powdered stuff ~
