Kumquat. A bitter little citrus fruit, originally from China and introduced to Corfu by botanist Sydney Merlin in 1846. Most of them grow in the north, around Nymfes. The island is the one place in Greece where they thrive, and where they make a diabolically sweet kumquat liqueur. You can also find jams, spoon sweets and even kumquats in the local cuisine. Corfu's kumquats are designated PDO (ΠΟΠ).
