Caper (Capparis spinosa)
[size=75]From Wikipedia, the free encyclopedia [/size]
The caper (Capparis spinosa L.) is a perennial spiny shrub that bears rounded, fleshy leaves and big white to pinkish-white flowers. A caper is also the pickled bud of this plant. The bush is native to the Mediterranean region, growing wild on walls or in rocky coastal areas throughout. The plant is best known for the edible bud and fruit (caper berry) which are usually consumed pickled. Other species of Capparis are also picked along with C. spinosa for their buds or fruits.
Capparis spinosa is highly variable in nature in its native habitats and is found growing near the closely related species C. sicula, C. orientalis, and C. aegyptia. Scientists can use the known distributions of each species to identify the origin of commercially prepared capers.[1][2]
The shrubby plant is many-branched, with alternate leaves, thick and shiny, round to ovate in shape. The flowers are complete, showy, with four sepals, and four white to pinkish-white petals, many long violet-colored stamens, and a single stigma usually rising well above the stamens.[3]
The salted and pickled caper bud (also called caper) is often used as a seasoning or garnish. Capers are a common ingredient in Mediterranean cuisine. The mature fruit of the caper shrub is also prepared similarly, and marketed as caper berries.
The buds, when ready to pick, are a dark olive green and about the size of a kernel of maize. They are picked, then pickled in salt, or a salt and vinegar solution.
Capers are a distinctive ingredient in Sicilian and southern Italian cooking, used in salads, pizzas, meat dishes and pasta sauces. Examples of uses in Italian cuisine are chicken piccata and salsa puttanesca. They are also often served with cold smoked salmon or cured salmon dishes (especially lox and cream cheese). Capers are also sometimes substituted for olives to garnish a martini.
Capers are categorized and sold by their size, defined as follows, with the smallest sizes being the most desirable: Non-pareil (0-7 mm), surfines (7-8 mm), capucines (8-9 mm), capotes (9-11 mm), fines (11-13 mm), and grusas (14+ mm).
