Bakers Specials' crystal size is even finer than that of fruit sugar. As its name suggests, it was developed specially for the baking industry. Bakers Special is used for sugaring doughnuts and cookies as well as in some commercial cakes to produce fine crumb texture. It is ideal for extra fine textured cakes and meringues, as well as for sweetening fruits and iced-drinks since it dissolves easily. In England, a sugar very similar to superfine sugar is known as caster or castor, named after the type of shaker in which it is often packaged.
Confectioners sugar is available in three grades ground to different degrees of fineness.
The confectioners sugar available in supermarkets is the finest of the three and is used in icings, confections and whipping cream. The other two types of powdered sugar are used by industrial bakers. Coarse sugar is normally processed from the purest sugar liquor. These characteristics are important in making fondants, confections and liquors. The large crystals reflect light and give the product a sparkling appearance.
