Stamps with the theme Bread & Baking

Bread, often referred to as the "staff of life" is a foodstuff made from grain that has been ground into flour or meal, then moistened and kneaded into a dough and baked. Some types of bread are leavened, mainly with yeast, which causes fermentation and makes the bread rise and expand. The ancient Egyptians are thought to have discovered methods of fermentation and they also invented baking ovens. Unleavened flat breads have been eaten since Neolithic times (10,000 B.C.), and bread has long been a mainstay in the diets of people in most parts of the world, except in areas of Asia, where the preferred rice is eaten in grain form.
