The flower bud of a bush native to the Mediterranean and parts of Asia. The small buds are picked, sun-dried and then pickled in a vinegar brine. Capers range in size from the petite nonpareil variety from southern France (considered the finest), to those from Italy, which can be as large as the tip of your little finger. There are also the Spanish-imported stemmed caperberries that are about the size of a cocktail olive. Capers are generally packed in brine but can also be found salted and sold in bulk. Capers should be rinsed before using to remove excess salt. The pungent flavor of capers lends piquancy to many sauces and condiments; they're also used as a garnish for meat and vegetable dishes.
