There is a company named "Dorot" that sells a line of frozen herbs, one of them being ginger. The herbs are ground, mixed with a tad of cornstarch and put into little "ice cube" trays, 3 inches by 4 inches, 20 cubes per tray. Each cube is a tbs of the herb. If your grocer carries them, they are wonderful. They are not quite as good as fresh, but they are 90% as good, and you don't have to peel them and you don't end up with 1/2 of your ginger root hiding behind the kale and getting fuzzy.
