When selecting fresh ginger look for ginger root that is firm to the touch and free of blemishes or mouldy ends. Avoid ginger that appears wrinkled as that is an indicator of age. If you use it often, wash and peel the ginger root and store it in an airtight container in the refrigerator and depending on its age when you bought it, it may last up to a month. If you only use it occasionally, wash and peel it, store it in the freezer and grate it as it is required.
