This hand crank 1 cup flour sifter breaks up and removes clumps from ingredients before baking or cooking. The crank handle rakes ingredients over the mesh screen to process ingredients quickly. Powdered ingredients, like baking flours and confectionary sugar tend to settle and compact during shipping. Mrs. Anderson’s Crank Flour Sifter aerates these ingredients and removes clumps for lighter, fluffier baked goods. Simply place the Flour Sifter over a bowl, mesh-side facing down, measure in the ingredients and turn the handle. It fluffs up finely powdered ingredients like all purpose flour, bread flour, cake flour, coconut flour and gluten free flour for lighter baked goods. This sifter also helps mix and blend in other ingredients evenly, like salt, baking soda, and baking powder, for an even consistency and better taste. Made from 18/0 stainless steel with a fine wire mesh. Hand wash in warm, soapy water and dry thoroughly.
