Calamansi is a hybrid between kumquat (formerly considered as belonging to a separate genus Fortunella) and another species of Citrus (in this case probably the mandarin orange).In parts of the United States, notably Florida and Hawaii, calamansi is also known as "calamondin", an old name from the American period of the Philippines.It is also used as an ingredient in dishes like sinigang (a sour meat or seafood broth) and kinilaw (raw fish marinated in vinegar and/or citrus juices).[15] Calamansi is also characteristically used as a condiment in almost all pancit dishes (Filipino noodles), which adds a citrusy sour flavor profile.[16] Calamansi is also a traditional ingredient in kesong puti, a native soft, unaged, white cheese made from carabao milk.[citation needed] In Malaysia and Singapore the fruit, known in Malay as limau kasturi[19] and in Malaysian and Singaporean English as "small lime", can be found paired with dishes at hawker centers and restaurants.It is primarily grown for its juice extracts which are exported to the United States, Japan, South Korea, Canada, and Hong Kong, among others.[20] Its cultivation has spread from the Philippines throughout Southeast Asia, India, Hawaii, the West Indies, and Central and North America, though only on a small scale.[23] The plant is sensitive to prolonged and/or extreme cold and is therefore limited outdoors to tropical, sub-tropical and the warmer parts of warm temperate climates, such as the coastal plain of the southeastern United States (USDA zones 8b - 11), parts of California, southern Arizona, southern Texas, and Hawaii.Potted plants are brought into a greenhouse, conservatory, or indoors as a houseplant during the winter periods in regions with cooler climates.
