In practice
Caster sugar (superfine sugar in the US) has smaller crystals than granulated, so it dissolves faster and gives a finer, lighter crumb in cakes and smoother meringues. A cup weighs around 220 g here. You can make it at home by pulsing granulated sugar in a food processor for a few seconds; measure by weight after grinding, since the volume changes. It is not powdered sugar, which has been ground much finer and contains cornstarch.
How to convert cups of caster sugar to grams
