Arabic cuisine has its roots in tent cookery. Nomadic tribes could use only transportable foods such as rice and dates, or ambulatory stock like sheep and camels in their recipes - which tended to be rough sketches rather than strict formulae.
As the caravans journeyed throughout the Middle East, new seasonings and vegetables were discovered and added to the existing repertoire. Each new discovery was incorporated into the diet in quantities palatable to a particular tribe - a fact that many cooks believe is responsible for the anomalies found in some Arabic dishes today.
