Why You Should Sift Flour
Putting your flour through a sifter will break up any lumps in the flour, which means you can get a more accurate measurement. Sifted flour is much lighter than unsifted flour and is easier to mix into other ingredients when making batters and doughs.
What is the purpose of a sifter?
What Does Sifting Flour Do? Sifting is a process that breaks up any lumps in the flour and aerates it at the same time by pushing it through a gadget that is essentially a cup with a fine strainer at one end.
Do I really need a sifter?
Now, most commercial flour is refined and clump-free, meaning there's no real need to sift it. (You should, however, use a kitchen scale to ensure that your cups of flour aren't way heavier than the recipe developer's.)
