History: The sesame plant likely originated in Asia or East Africa, and ancient Egyptians are known to have used the ground seed as grain flour. The seeds were used by the Chinese at least 5,000 years ago, and for centuries they have burned the oil to make soot for the finest Chinese ink blocks. Usage: Sesame seed is a common ingredient in various cuisines. It is used whole in cooking for its rich, nutty flavour. Sesame seeds are sometimes added to bread, including bagels and the tops of hamburger buns. They may be baked into crackers, often in the form of sticks.
