Caster sugar is a fine sugar from the United Kingdom and is called so because the grains of this sugar are so small, that they can fit in the holes of a caster. In the United States of America, it is called superfine sugar though it is not as fine as the mechanically ground sugar. Its main characteristic is that it dissolves easily in cold liquids also. This sugar is known by both the names, castor sugar and caster sugar. This sugar is finely pulverized and dissolves faster than the standard granulated sugar. You can make this sugar at home too. Just grind regular sugar in a food processor, the outcome will be castor sugar. It is used in meringues, mousses, and soufflés, and in beverages that are not cooked.
