The durian (/ˈdʊəriən/, /ˈdjʊəriən/)[2] is the edible fruit of several tree species belonging to the genus Durio. There are 30 recognised Durio species, at least nine of which produce edible fruit.[3][4] Durio zibethinus, native to Borneo and Sumatra, is the only species available in the international market. It has over 300 named varieties in Thailand and 100 in Malaysia, as of 1987. Other species are sold in their local regions.[3] Durians are commonly associated with Southeast Asian cuisine, especially in Indonesia, Malaysia, Singapore, Thailand and Vietnam.
Named in some regions as the "king of fruits",[4][5] the durian is distinctive for its large size, strong odour, and thorn-covered rind. The fruit can grow as large as 30 centimetres (12 inches) long and 15 cm (6 in) in diameter, and it typically weighs 1 to 3 kilograms (2 to 7 pounds). Its shape ranges from oblong to round, the colour of its husk green to brown, and its flesh pale yellow to red, depending on the species.
An acquired taste, some people regard the durian as having a pleasantly sweet fragrance, whereas others find the aroma overpowering and unpleasant. The smell evokes reactions from deep appreciation to intense disgust, and has been described variously as rotten onions, turpentine, and raw sewage. The persistence of its odour, which may linger for several days, led certain hotels and public transportation services in Southeast Asia to ban the fruit. The nineteenth-century British naturalist Alfred Russel Wallace described its flesh as "a rich custard highly flavoured with almonds". The flesh can be consumed at various stages of ripeness, and it is used to flavour a wide variety of savoury and sweet desserts in Southeast Asian cuisines. The seeds can also be eaten when cooked.
The name "durian" is derived from the Malay word dūrī (meaning 'thorn'), a reference to the numerous prickly thorns on its rind, combined with the noun-building suffix -an.[6][7] According to the Oxford English Dictionary, the alternate spelling durion was first used in a 1588 translation of The History of the Great and Mighty Kingdom of China and the Situation Thereof by the Spanish explorer Juan González de Mendoza:[6]
There is one, yt is called in the Malaca tongue Durion, and is so good that [...] it doth exceede in savour all others that euer they had seene, or tasted.
Other historical variants include duryoen, duroyen, durean, and dorian.[6] The name of the type species, Durio zibethinus, is derived from Viverra zibetha (the large Indian civet), a mammal known for its odour.[8]
