The best way to prepare Sushi Ginger is to soak it in vinegar. You can add pickling sugar or red wine vinegar. These vinegars will improve the flavor and color of the sushi ginger. The ginger should be left in the refrigerator for at least a month. Once it's been picked, it will keep for at least a month. To preserve it for longer, you can also use it as a stir fry sauce. It will give your sushi a nice, fresh taste.
