Flour is used as the main ingredient for many types of food items including breads, rolls, biscuits, pancakes, waffles, cakes, pastries, and pasta. Some food items, such as cakes, waffles, and pancakes, require only a batter to be created, which is usually liquid enough to be poured, while foods such as breads, rolls, and pasta require a dough to be formed, which is a heavier mass that usually requires some kneading or rolling.
