The kumquat fruit looks like an oval tiny orange approx. 3-4 cm long.

It is the only fruit of the Citrus family that is eaten with the peel, which is rich in essential oils and vitamin C. Its distinctive bittersweet zesty flavour makes it the perfect ingredient in deserts and salads and as a marmalade and preserve.
Corfu, Greece is one of the only places in Europe where kumquat is cultivated.

koum kouat, kum quat, koum quat, koumkat, kumqouat, kumquat.
