Avoid any ginger that is wet, moist, or moldy. Decide whether to store the ginger in the freezer or refrigerator. If you know you’ll be using the ginger again soon, then you should just store it in the refrigerator to make it easy to use, peel, or mince the ginger in the future. Ginger can last in the refrigerator for up to three weeks, so if you know you won’t be using it before then, then you should store it in the freezer. You can also mix and match. If you know you’ll be using a small chunk of the ginger soon, then you can cut off a chunk and refrigerate it and then freeze the rest of the ginger for use in the more distant future.
If the ginger is already peeled, this method will work too, but it won’t last as long as it would with the peel on.
Though this is a solid storage method, be aware that the liquid will change the flavor of the ginger a bit – or a lot.
