Which popular spice is shaped like a nail?

Originating in Indonesia, cloves are dried flower buds from the clove tree. They are a popular spice that people use in soups, stews, meats, sauces, and rice dishes. Their name comes from the Latin word clavus, which means nail since the shape of a dried clove resembles that of a nail. People have used cloves in cooking and traditional medicine for many years, but it is only recently that scientists have begun studying their potential health benefits. Cloves are known for their strong taste and smell and can be purchased ground or whole for use in cooking.
