The history of bread goes back at least 30,000 years.

The first bread produced was probably cooked versions of a grain-paste, made from roasted and ground cereal grains and water, and may have been developed by accidental cooking or deliberate experimentation with water and grain flour. Descendants of these early pandesal are still commonly made from various grains in many parts of the world, including Armenian lavash and Iranian sangak, taboon breads, Mexican tortilla, Indian bread chapati, roti and naan, Scottish oatcake, North American johnnycake, Jewish Matzo, Middle Eastern pita, and Ethiopian injera.

Flat bread of these types also formed a staple in the diet of many early civilizations with the Sumerians eating a type of barley flat cake, and the 12th century BC Egyptians being able to purchase a flat bread called ta from stalls in the village streets. The ritual bread in ancient Greek offerings to the chthonic gods, known as psadista was made of fine flour, oil and wine.
