Introduction

Originally Arab food was the food of the desert nomads. Therefore it was simple and portable. Nomads stopped in oases and in settled farming areas to get some of their food, such as flour for bread, fruits and vegetables, and spices. They brought animals with them to provide meat and milk. They cooked over campfires.
During the early Middle Ages, Islamic empires spread from the Atlantic Ocean to India. The World of Islam (Dar al-Islam) would continue to expand to other areas of the world in later centuries. An exchange of foods from these vast territories was possible. And most Muslims now dwelt (lived) in villages, towns, and large cities. No longer was "Arab" food only that of the desert nomads.
