How do you dry fresh whole ginger root?

To dry fresh whole ginger root, first, wash and peel the ginger, then slice it into thin pieces to facilitate even drying. Spread the slices on a baking sheet or dehydrator tray in a single layer, ensuring they aren't overlapping. Dry the ginger in a dehydrator at around 135°F (57°C) or in an oven set to the lowest temperature, checking periodically until the pieces are completely dry and brittle. Once dried, store the ginger in an airtight container in a cool, dark place.
