Native to India, ginger root grows underground. Ground ginger is easier to use and measure than fresh; it keeps well and there’s no need to peel before using. But ground ginger is slightly milder than the pungent spice of the root, making it great for cookies and cakes. Add its hot, spicy deliciousness to Asian stir fries too. Keep ginger on hand to help settle a queasy stomach, colds and flu, and arthritis flare-ups.
