Castor (or Caster Sugar) is very fine granulated sugar, so named because the grains are small enough to fit though a sugar "caster" or sprinkler. Because of its fineness, it dissolves more quickly than regular white sugar, and is especially useful in meringues, custards, mousses, and for sweetening cold drinks or cocktails. Castor Sugar is also used in baking.
