Sifting powdered sugar is a crucial step in baking, ensuring that the sugar is evenly distributed and free of lumps. Powdered sugar, also known as confectioners’ sugar or icing sugar, has a fine texture and easily clumps when stored, making it difficult to use directly from the bag.
Sifting powdered sugar eliminates lumps, which can result in uneven sweetness and an undesirable grainy texture in baked goods. Sifting also aerates the sugar, creating a lighter and fluffier texture. This is especially important for frostings, glazes, and icings, as a smooth, lump-free consistency is essential for a professional finish.
