Flour sieves and flour sifters are common kitchen tools found in commercial kitchens and bakeries, used to take out clumps from flour and sugar. Using a flour sifter or sieve also enables you to aerate your flour, which gives baked goods a light and fluffy texture. You can also seamlessly blend other dry ingredients to the flour when you sift ingredients together. A flour sieve, with its fine mesh lining, can also be used for straining a variety of food items.
