/ 250 g caster sugar

Caster sugar, also known as superfine sugar or castor sugar, is a granulated sucrose sweetener with exceptionally fine crystals, smaller than standard granulated sugar but larger than powdered sugar. Derived from sugar cane or sugar beets, caster sugar is processed to achieve a uniform grain size of approximately 0.5 mm, making it finer than common table sugar. This refined texture allows for more rapid dissolution and even distribution in batters, creams, and beverages. The ingredient is particularly valued in European and Commonwealth baking traditions.

Caster sugar is the preferred sweetener in baking and confectionery, particularly for meringues, mousses, whipped creams, and delicate cake batters where rapid dissolution is essential. Its fine crystals incorporate smoothly into egg whites and incorporate less air than coarser sugars, making it ideal for producing glossy meringues and stable foams. It is widely used in cocktails, desserts, and fine pastry work across British, European, and Commonwealth cuisines. The ingredient dissolves quickly in cold liquids and creates a smoother texture in custards, mousses, and buttercreams compared to standard granulated sugar.
