tea-spoonful of powdered sugar
Powdered sugar is essentially pure carbohydrate with negligible amounts of other nutrients; it provides approximately 31 calories per teaspoon with no fiber, protein, or micronutrient content beyond trace minerals from processing.
About
Powdered sugar, also known as confectioners' sugar or icing sugar, is granulated sucrose that has been ground to an extremely fine powder and mixed with a small amount of cornstarch or anti-caking agents to prevent clumping. Derived from sugarcane or sugar beets, this refined sweetener is nearly pure crystalline glucose with minimal impurities. The fine particle size and added starch distinguish it from standard granulated sugar, making it particularly suited for applications requiring smooth integration without visible crystals. The cornstarch content typically comprises 3-5% by weight in commercial preparations.
Culinary Uses
Powdered sugar is essential in pastry and baking applications where a smooth, lump-free texture is required. It is the primary ingredient in royal icing, buttercream frostings, and glazes, where its fine texture dissolves seamlessly into wet ingredients. In confectionery, it serves as the base for fondants, fudges, and dusted finishes on baked goods and candies. Powdered sugar is also used in whipped cream, meringues, and as a finishing garnish dusted over desserts for visual appeal. Its lower density compared to granulated sugar allows for more precise volumetric measurement in delicate applications.
