Caster sugar, also known as superfine sugar or castor sugar, is a refined crystalline sucrose product derived from sugar cane or sugar beets. The crystals are finer than granulated sugar but coarser than powdered sugar, typically measuring between 0.5 and 1.5 millimeters. This intermediate crystal size is achieved through specialized grinding and sieving processes during refining. The result is a white, free-flowing sweetener with a slightly finer texture than standard table sugar, dissolving more readily in liquids and batters while maintaining its granular structure. Caster sugar has a neutral, purely sweet flavor with no molasses notes.

Caster sugar is the preferred sweetener in baking and confectionery due to its superior dissolution properties and ability to incorporate air during creaming. It is essential in meringues, mousses, and whipped desserts, where its fine crystals dissolve easily into egg whites and cream. In British and European baking traditions, caster sugar is standard for cakes, cookies, and pastries. It is also widely used for sweetening beverages, dusting desserts, and making syrups and caramel. Its fine grain allows for more uniform incorporation into delicate batters and toppings than coarser sugars.
