Caster Sugar
Description
Caster sugar, known as 'castor' in some countries, 'superfine sugar' in the United States, or 'berry sugar' in Canada, is a type of granulated sugar that is finer than regular granulated sugar but not as fine as powdered sugar. It dissolves more quickly than regular sugar, making it ideal for meringues, soufflés, and light sponge cakes. In recipes, caster sugar is often measured by weight, with common European units such as grams (g), and by volume, with American units like cups (c) and tablespoons (tbsp).
In Europe, recipes might call for 100g of caster sugar, while in American recipes, the same amount could be listed as 1/2 cup. To convert, 1 cup of caster sugar is roughly equivalent to 200g. Regardless of the units used, the role of caster sugar in achieving the desired texture and sweetness in culinary preparations remains the same.
Common uses
Caster sugar is primarily used in baking and confectionery, where its fine crystals are prized for their quick-dissolving properties. It is also used in cocktails and other beverages that require a sweetener that will easily blend without leaving a gritty texture.
