Sesame — Sesame (Sesamum indicum) is a flowering plant in the genus Sesamum. The precise natural origin of the species is unknown, although numerous wild relatives occur in Africa and a smaller number in India. It is widely naturalised in tropical regions around the world and is cultivated for its edible seeds.
It is an annual plant growing to 50 to 100 cm (2-3 feet) tall, with opposite leaves 4 to 14 cm (5.5 in) long with an entire margin; they are broad lanceolate, to 5 cm (2 in) broad, at the base of the plant, narrowing to just 1 cm (half an inch) broad on the flowering stem. The flowers are white to purple, tubular, 3 to 5 cm (1 to 2 in) long, with a four-lobed mouth.
Sesame is grown primarily for its oil-rich seeds, which come in a variety of colors, from cream-white to charcoal-black. In general, the paler varieties of sesame seem to be more valued in the West and Middle East, while the black varieties are prized in the Far East. The small sesame seed is used whole in cooking for its rich nutty flavour (although such heating damages their healthful poly-unsaturated fats), and also yields sesame oil.
