Crystallized (or candied) ginger is ginger root that has been peeled, sliced, poached in sugar syrup and coated with sugar crystals.

It has a sweet, spicy bite and is often used in desserts, such as candied ginger ice cream. It can also be nibbled on its own as a sweet snack or an accompaniment to tea. (Ginger is said to aid digestion and help relieve upset tummies.)

You can buy crystallized ginger in most major supermarkets now. If you strike out there, try a local Asian grocery. Or make it yourself.
