Kumquat

The edible golden orange rind is sweet, while the rather dry flesh is very tart. The entire fruit-skin and flesh-is eaten, and very ripe fruit can be sliced and served raw in salads or as a garnish. The kumquat is more likely to be found cooked, however, either candied or pickled whole or in preserves or marmalades. Kumquats contain good amounts of potassium and vitamins A and C.
