Related to Icing Sugar

Sugar

Granulated sugar is the coarse crystal that icing sugar is milled from, and it is heavier per cup (200 g vs 125 g), so it will not dissolve smoothly in frostings. Blend it to a fine powder first, or weigh rather than swapping by volume. See our Sugar converter.

Raw Sugar

Raw sugar has large, coarse crystals with a faint molasses taste, far removed from the fine powder of icing sugar. It packs much heavier (200 g vs 125 g per cup), so the two are not a straight swap. See our Raw Sugar converter.
