Caster sugar意思

Caster sugar, also known as castor sugar, is a type of sugar that is finely ground and often used in baking and cooking. It is named after the caster or shaker top that it is often sold in, which makes it easy to sprinkle over food or to measure out small amounts. Caster sugar is similar to superfine sugar, and it dissolves easily in liquids, making it ideal for use in cocktails, iced tea, and other beverages. It is also commonly used in baking, especially in recipes that require a lot of sugar to dissolve quickly, such as meringues and macarons.
