If you have ever seen someone making bread, you may have wondered what flour is. Flour is quite simply finely ground wheat. White flour is made from wheat that has been thrashed, removing its outer skin and chaff. It is also often bleached to enhance its whiteness. Whole wheat flour has a more brownish color and a stronger texture since its chaff and bran have been left in. Flour has numerous uses throughout the world, and has been around since ancient times. The most common use of flour is in making bread and pasta. It can also be used to thicken sauces and bake a wide variety of desserts and pastries.
