powered sugar
Powdered sugar is essentially pure carbohydrate with minimal micronutrients; the cornstarch component adds negligible fiber. One tablespoon (7g) contains approximately 27 calories and 7g of sugar with no significant vitamins or minerals.
About
Powdered sugar, also known as confectioners' sugar or icing sugar, is refined white granulated sugar that has been ground to an extremely fine powder and mixed with a small amount of cornstarch or anti-caking agent. The ingredient originated in Europe during the 17th century as kitchen technology advanced, enabling the production of ultra-fine sugar crystals. Powdered sugar dissolves rapidly in liquids and creates smooth, lump-free mixtures, making it ideal for applications requiring a fine texture. The cornstarch addition (typically 3-5% by weight) prevents clumping and moisture absorption during storage.
Culinary Uses
Powdered sugar is essential in confectionery and pastry work, primarily used for dusting baked goods, creating glazes, frostings, and fillings. It is the primary ingredient in royal icing, buttercream, and fondant, where its fine particle size ensures smooth, silky finishes. In beverages, it dissolves readily into cold liquids without grittiness. It is also used for dusting donuts, churros, and desserts. In professional baking, it provides consistent results due to its uniform particle size and reliable dissolution properties.
