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.
Brown Sugar
Brown sugar is caster sugar's opposite in the creaming bowl: damp, clumping, and pressed into the cup instead of levelled off. Swap it in and the molasses brings moisture with it, so a sponge built for caster comes out denser, darker, and slower to dry out. See what 1 ounce of brown sugar is in grams.
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.
