About caster sugar
Caster sugar is a finely granulated white sugar produced by refining sugar cane or sugar beet. It dissolves quickly and easily, making it ideal for baking, whipped creams, and beverages. The fine crystals incorporate air efficiently when creaming butter and sugar, creating light, fluffy cakes and biscuits. Its neutral flavour and rapid dissolution distinguish it from coarser sugars, though it functions similarly in most recipes.
