Kumquat

The kumquat (Fortunella, also in the genus Citrus) is a small fruit-bearing tree in the rue family, Rutaceae. The edible fruit of the tree resembles a small orange, but is oval-shaped, 1–2 inches long, and is generally tart. The name "kumquat" derives from the Cantonese gam gwat (金橘), meaning "golden orange". In Hebrew, the fruit is known as קומקוואט (kumkv'at). Other relevant translations include cumquat in French, kumquat in Spanish, and goldorange in German. The fruit is typically eaten whole, either fresh or candied, and its high concentration of citric acid gives the fruit a sweet-tart flavor. Kumquats are often candied or used in jellies and jams, and their rind is used in marmalade. The tree is native to Southeast Asia, and is now widely cultivated in greenhouse and conservatory settings.
