These are the fruits of the caper bush and are native to the Mediterranean. They are oblong in shape and a green colour and are slightly larger than a grape. Caperberries are often consumed in pasta dishes or salads but they can also be pickled in brine, like olives, and eaten as they are. The lemony taste has been described as slightly milder than a caper. Caperberries contain good levels of antioxidants as well as important vitamins and minerals such as iron.
