Superfine sugar is favored for sweetening drinks or preparing a meringue. Caster sugar is the name of very fine sugar in Britain, so named because the grains are small enough to fit though a sugar "caster" or sprinkler. It is sold as "superfine" sugar in the United States.
Because of its fineness, it dissolves more quickly than regular white sugar, and so is especially useful in meringues and cold liquids. It is not as fine as confectioner’s sugar, which has been crushed mechanically (and generally mixed with a little starch to keep it from clumping).
If the recipe calls for superfine, powdered, or brown sugar, you can actually make any of them at home from regular white sugar. "If you don't have it in the house, you don't have to run out to the store—it's totally fine to make it yourself, All you need is a blender (or food processor) and a bit of ingenuity.

How to Make Superfine Sugar
f you don’t have any caster sugar on hand, you can make your own by grinding granulated sugar for a couple of minutes in a food processor (this also produces sugar dust, so let it settle for a few moments before opening the food processor). For one cup: Grind one cup and two teaspoons of white granulated sugar in a blender, coffee bean type grinder or food processor for 30 seconds.
Rimming the Glass with Sugar
Many cocktails, including our lemon drop cocktail, call for rimming the glass with superfine sugar. The rim of the glass is moistened just a bit and then dipped into the superfine sugar. Lightly tap the side of the glass to remove any excess sugar.
