A Caper (Capparis spinosa) is a shrub from the Mediterranean region. It is best known for its edible buds and fruit which are usually consumed pickled.
The pickled or salted caper buds (also called capers) are often used as a seasoning or garnish. Capers are a common ingredient in Mediterranean cuisine. The grown fruit of the caper shrub is also available, prepared similarly to the buds, as caper berries.
The berries, when ready to pick, are a dark olive green and about the size of a kernel of corn. They are picked and then pickled in a vinegar and salt solution. Capers are often enjoyed in cold smoked salmon or cured salmon dishes, salad, and also pasta.
