About
Caster sugar, also known as superfine sugar or baker's sugar, is a refined granulated sugar with exceptionally fine crystals, typically measuring between 0.3 and 0.5 millimeters in diameter. Derived from sugarcane or sugar beets, caster sugar is produced through crystallization and centrifugal separation processes that create uniform, small granules. The fine crystal structure distinguishes it from standard granulated sugar, enabling faster dissolution and more even distribution in batters, doughs, and beverages. Its name derives from its traditional use in caster or shaker dispensers. Caster sugar is chemically identical to regular granulated sugar (sucrose) but offers distinct practical advantages in baking and confectionery work due to its particle size.
Culinary Uses
Caster sugar is the preferred sweetener in baking applications where rapid dissolution and smooth texture are paramount. It is particularly valued in meringues, mousses, whipped cream, and cake batters, where its fine crystals dissolve instantly without leaving grittiness. In custards, creams, and frostings, caster sugar creates superior mouthfeel compared to coarser granules. It is also commonly used in beverages such as iced tea and cocktails, where quick dissolving is essential. Beyond sweet applications, caster sugar is employed in spice rubs and savory glazes where its fine texture ensures even coating and rapid caramelization.
