Cloves are a pungent spice found in savory dishes, desserts, and drinks. Ground or whole cloves flavor meat, sauces, and rice dishes. Cloves are often used along with cinnamon and nutmeg in sweet dishes, especially "pumpkin pie" flavored items for the autumn and winter holidays, and in drinks such as mulled wine, cider, or chai.
Cloves are a spice made from the flower buds of an evergreen tree called, appropriately enough, the clove tree (Syzygium aromaticum). Clove flower buds are harvested in their immature state and then dried. Whole cloves are shaped like a small, reddish-brown spike, usually around 1 centimeter in length, with a bulbous top. Cloves can be used whole or ground, and they have a very strong, pungent flavor and aroma.
Whole or ground cloves are used to flavor sauces, soups and rice dishes, notably a number of traditional Indian dishes, and it's one of the components of garam masala. Whole cloves are either removed before serving or picked out of the dish. Even when cooked, whole cloves have a very hard, woody texture that would be unpleasant to bite into. Cloves also feature in any number of desserts, especially ground cloves, and particularly around the holidays. Think eggnog or pumpkin pie spice. Cloves are often paired with cinnamon or nutmeg, but in general, it's a good idea to use cloves sparingly.
