Fresh ginger is a spicy, aromatic rhizome popular in many Asian dishes. Its flesh may be yellow, white or red. Mature ginger has a thick brown skin, a firm texture and a pungent taste. Ginger will become soft and wrinkled as it gets old, but as long as you store it properly, it can last over two months in the refrigerator or up to six months in the freezer. Ginger preserved by drying or candying will last even longer.
Store ginger you intend to use within a few weeks in the crisper drawer of your refrigerator. Place it unpeeled in a resealable plastic bag and seal it tightly. It should stay fresh for several weeks.
To keep the ginger on hand for more than a few weeks, place it in an empty jar and fill the jar with vodka. Seal the jar and store it in your refrigerator. In an experiment by Fine Cooking, ginger stored in vodka kept its texture and flavour for over eight weeks.
Seal unpeeled, fresh ginger in a resealable plastic freezer bag and freeze it if you intend to keep it for several months and use it later. According to WH Foods, unpeeled ginger will keep for up to six months in the freezer.
Fresh ginger is a traditional herbal remedy for stomach troubles such as indigestion and nausea.
Don't use fresh ginger that has become mouldy, soft or wrinkled.
