Flour is a powder made by grinding raw grains, roots, beans, nuts, or seeds but are commonly made from Wheat, Rice Pulses and Millets.
Cereal flour is the main ingredient of bread, which is a staple food for most cultures. Wheat flour is one of the most important ingredients in many cultures, and is the defining ingredient in their styles of breads and pastries.
Rice flour is a form of flour made from finely milled rice. Rice flour is a common substitute for wheat flour. It is also used as a thickening agent in recipes that are refrigerated or frozen since it inhibits liquid separation.
