Related to Sugar
Caster Sugar
Caster sugar swaps 1:1 by volume for granulated sugar and dissolves faster thanks to its finer grain, which helps in meringues and delicate sponges. They weigh close per cup (225 g caster vs 200 g granulated), so measure by weight for the most exact match. See our Caster Sugar converter.
Brown Sugar
Brown sugar swaps 1:1 by volume for granulated sugar and adds moisture and a caramel note from its molasses. Packed, it weighs more per cup (220 g vs 200 g), so weigh it when you want the texture and sweetness to land the same. See our Brown Sugar converter.
Raw Sugar
Raw sugar swaps 1:1 by volume for granulated sugar with a coarser crystal and faint molasses taste. It can leave a little crunch in delicate bakes, so dissolve it into the wet ingredients first when you want a smooth, even crumb. See our Raw Sugar converter.
Icing Sugar
Icing sugar is granulated sugar ground to a powder, used for frostings and dusting rather than creaming into batters. It packs lighter (125 g vs 200 g per cup), so the two are not a straight 1:1 swap. See what 1 ounce of icing sugar is in cups.
