package powdered sugar

Powdered sugar, also known as confectioners' sugar or icing sugar, is refined white sugar that has been ground into an extremely fine powder and mixed with a small amount of anti-caking agent, typically cornstarch (approximately 3% by weight). The ingredient derives from cane or beet sugar that undergoes crystallization and mechanical grinding to achieve a texture fine enough to dissolve instantly and create smooth, lump-free frostings and glazes. The cornstarch addition prevents clumping during storage and handling, distinguishing it from granulated sugar. Powdered sugar dissolves readily in minimal liquid, making it the preferred sweetener for applications requiring a smooth, uniform consistency.

Powdered sugar is the primary sweetening agent for frostings, glazes, icings, and fondants in baking and pastry work. It is commonly dusted over finished cakes, cookies, and pastries for decoration and sweetness, or mixed with liquid (milk, water, egg whites) to create smooth spreads and glazes for layer cakes, donuts, and other baked goods. Beyond baking, it is used in confectionery work for creating smooth coatings, in beverages like sweetened cocktails and hot chocolate, and as a finishing garnish for desserts. Its fine texture makes it essential in Swiss meringue buttercream and royal icing, where lumpiness would compromise the final product.
