Capers are pickled flower buds of a shrub native to the Mediterranean and also parts of Asia. Usually they are packed in brine but can also be preserved in salt. They should be rinsed before use to remove excess salt.
Use: The pungent flavour of capers adds a tang to many sauces and condiments (eg tartare sauce), they can also be used as a garnish for meat and vegetable dishes and in tapenade.
