Mrs. Anderson's Crank 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 confectioners' 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. No more lumps! Simply place the Flour Sifter over a bowl, mesh-side facing down.
