About Powdered Sugar

Powdered sugar's 25% swing between sifted and unsifted is the largest in this database — and icing recipes feel every gram. When a recipe says "2 cups sifted," sift first then measure; "2 cups, sifted" means measure then sift. The cornstarch in it (anti-caking) matters in cooked applications — it thickens glazes slightly.
