Coriander

Coriander is an annual herb in the family Apiaceae. It is also known as cilantro, particularly in the Americas. Coriander is native to southwestern Asia west to north Africa. It is a soft, hairless plant growing to 50 cm [20 in.] tall. The leaves are variable in shape, broadly lobed at the base of the plant, and slender and feathery higher on the flowering stems. The flowers are borne in small umbels, white or very pale pink, asymmetrical, with the petals pointing away from the centre of the umbel longer (5-6 mm) than those pointing to the middle of the umbel (only 1-3 mm long). The fruit is a globular dry schizocarp 3-5 mm diameter.

All parts of the plant are edible, but the fresh leaves and the dried seeds are the most commonly used in cooking. Coriander is commonly used in Middle Eastern, Mediterranean, Indian, South Asian, Mexican, Latin American, Chinese, African and Southeast Asian cuisine. Coriander leaves were formerly common in European cuisine but nearly disappeared before the modern period. Today western Europeans usually eat coriander leaves only in dishes that originated in foreign cuisines, except in southern Portugal, where they are still an essential ingredient in many traditional dishes.

Coriander seed is a key spice in garam masala and Indian curries, which often employ the ground fruits in generous amounts together with cumin. It also acts as a thickener. Roasted coriander seeds, called dhana dal, are also eaten as a snack. It is also the main ingredient of the two south Indian gravies: sambhar and rasam. Coriander seeds are also used in brewing certain styles of beer, particularly some Belgian wheat beers. The coriander seeds are typically used in conjunction with orange peel to add a citrus character to these styles of beer.

Coriander grows wild over a wide area of the Near East and southern Europe, which forced Zohary and Hopf to admit that "it is hard to define exactly where this plant is wild and where it only recently established itself." Fifteen desiccated mericarps were found in the Pre-Pottery Neolithic B level of the Nahal Hemel Cave in Israel, which may be the oldest archeological find of coriander. About half a litre of coriander mericarps were recovered from the tomb of Tutankhamun, and because this plant does not grow wild in Egypt, Zohary and Hopf interpret this find as proof that coriander was cultivated by the ancient Egyptians. The Bible mentions coriander in Exodus 16:31: "And the house of Israel began to call its name Manna: and it was round like coriander seed, and its taste was like that of flat cakes made with honey."
