Related to Caster Sugar
Sugar
Granulated sugar swaps 1:1 for caster sugar in most recipes, though its larger crystals dissolve more slowly. For meringues or smooth sponges, pulse granulated sugar in a food processor for a few seconds to bring it closer to caster's finer grain. See our Sugar converter.
Icing Sugar
Icing sugar is milled far finer and packs much lighter than caster (125 g vs 225 g per cup), so it is not a 1:1 swap. Use it only where a powder works, such as uncooked frostings and dusting, not for creaming into a cake batter. See our Icing Sugar converter.
Raw Sugar
Raw sugar has large, coarse crystals that dissolve slowly, the opposite of fine caster sugar. It packs lighter (200 g vs 225 g per cup), so it is not a 1:1 swap by volume; weigh when substituting. See our Raw Sugar converter.
