While capers are a familiar addition to salads and other dishes, where they come is a mystery to many people. In fact, the salty food item — often used as a flavoring agent — is a pickled version of the buds from the caper bush. According to,  the flowers are picked from the bush long before flowering. They are sun-dried and then brined or packed in dry salt, giving them their distinct taste. Capers that have matured to a small fruit are called caper berries. These are also brined, and can be eaten or used the way olives are.

Commonly used in Mediterranean cuisine, capers are widely-grown in that region, as well as in nearby areas including north Africa, southern Europe, the Middle East, Asia, and Turkey. In the United States, capers are grown chiefly in California.

Harvesting capers can be tedious, as they are too small and fragile to be picked by anything else other than human hands. Because of this, capers can be expensive. They have an olive green color, are usually sold in jars or bottles, soaked in their brining liquid, or in vinegar. Capers in dry salt are harder to find, available only in specialty stores or by special order.
