As the dominant symbol of Passover is the eating of the "bread of affliction," or flat matzoh, during the entire holiday, the preparation of the matzoh in Orthodox communities extends back to watching the fields in which the grain is grown, to make sure that none of it becomes fermented through rotting. The flat cakes of the Exodus were hastily made from dough that was not set aside to ferment and rise -- and one may indeed see the Bedouin of the Sinai today making the same flat bread, or pittah, from a dough of flour and water that is at once baked over a small fire. Levin 1969, p 21
Sephardi matzah is more like pittah.
