A Caper (Capparis spinosa) is a shrub from the Mediterranean region. It is best known for its edible buds and fruit which are usually pickled or salted.

The pickled or salted caper bud (also called caper) is often used as a seasoning or garnish. Capers are a common ingredient in Mediterranean cuisine.

Capers are often enjoyed in cold smoked salmon or cured salmon dishes, salad, pizza, pasta and sauces. Capers are also sometimes substituted for olives to garnish a martini.
