How to Purchase Ginger
Look for gingerroot with a smooth skin and a fresh, spicy fragrance. Wrinkles indicate that the root is dry and past its prime.
How to Store Ginger
Wrap up fresh unpeeled gingerroot in plastic wrap and store in refrigerator for up to 3 weeks. Or, freeze for up to 6 months. To use frozen ginger, slice off the amount of root needed (while still frozen), then return the unused piece immediately to the freezer.
Substitute 2 tsp. ground ginger for the grated gingerroot.
