g/3oz icing sugar
Icing sugar is a refined carbohydrate that provides quick energy but contains negligible micronutrients; it should be used primarily as a sweetening agent rather than a nutritional source.
About
Icing sugar, also known as powdered sugar, confectioners' sugar, or 10x sugar, is a finely ground refined sugar made from granulated white sugar that has been pulverized to an extremely fine powder. This ingredient typically contains a small percentage of cornstarch or anti-caking agents (usually 3-5%) to prevent clumping and maintain a free-flowing consistency. The powder is so fine that it dissolves instantly in liquids and creates a smooth, lump-free texture when combined with fats and liquids, making it ideal for creating silky frostings, glazes, and icings. The slight cornstarch content distinguishes it from castor sugar and other granulated varieties.
Culinary Uses
Icing sugar is the primary sweetener in frostings, buttercreams, glazes, and icing for cakes, cookies, and pastries. It is dusted over desserts for decoration and used to create smooth, spreadable fillings for sandwich cookies and layered cakes. In traditional recipes, icing sugar combined with egg whites produces royal icing for piping decorative details on gingerbread and wedding cakes. It is also used in fondant, marzipan, and meringue preparations. Beyond desserts, it sweetens beverages and is occasionally used in savory applications such as dusting game meats or seasoning salads.
