Sugar is a finely ground sugar made by milling normal granulated sugar into a powdered state. It contains a small amount of anti-caking agent to prevent clumping and improve flow.
In industrial food production, it is used where a quick dissolving sugar is required. Domestically, it is principally used to make icing or frosting and other cake decorations. It is often lightly dusted onto baked goods to add a light sweetness and subtle decoration.
