Capers are the edible flower buds of the caper bush and are native to the Mediterranean. They are oblong in shape and a dark green colour and are similar in size to an olive. Capers are often consumed in pasta and meat dishes or salads but they can also be pickled in brine, like olives, and eaten as they are. They have a slightly stronger taste than caperberries. Capers contain good levels of antioxidants as well as important vitamins and minerals such as iron.
