Powdered sugar
Powdered sugar (in
Britain,
Australia and most of the
Commonwealth icing sugar) is a very finely ground form of
sugar that is synonymous with
confectioner's sugar. In industrial food production it is used where a quick dissolving sugar is required or as in domestic use principally to make
icing or
frosting, and other cake decorations. It is often lightly dusted onto a baked good to add light sweetness and subtle decoration. It is generally mixed with
cornstarch or wheat
flour, or
calcium phosphate to improve its flowing ability and is not generally used to sweeten a beverage, but producers do make industrial grades available without additives.
Caster sugar, generally unavailable in the
United States, is a larger particle size approximately half or less in size of granulated.
Powdered sugar is made from milling, and selective sieving of granulated sugar.
Powdered sugar is a
disaccharide.
