Confectioner's sugar, also known as powdered sugar or icing sugar, is a fine, powdery sugar that is commonly used in baking. It is typically made by grinding granulated sugar into a fine powder and then adding cornstarch to prevent clumping. However, there are several other synonyms used for confectioner's sugar in different regions of the world. In the UK, it is often referred to as caster sugar or icing sugar, while in Australia and New Zealand, it is called icing sugar or pure icing sugar. Other synonyms include powdered icing sugar, 10X sugar, and snow sugar. Regardless of the name, this type of sugar is an essential ingredient in many desserts, particularly frosting and glazes.
