Kumquat
The Kumquat fruit, also known as the “Chinese mandarin” or “fortunella,” has the characteristic of being all one pulp and peel; in fact, it is eaten whole, with the entire peel, to savor its typical sweet sour taste. It can be eaten fresh, au naturel, but it is also delicious candied and as a base for jams and fruit salads.
In the Northern Hemisphere it tends to be marketed from November to February.
