What is confectioners’ sugar?

Confectioners’ sugar, also known as powdered sugar or icing sugar, is a finely ground form of sugar that is often used in baking and frosting recipes. It is typically made by grinding granulated sugar into a fine powder and is frequently combined with a small amount of starch to prevent clumping. The texture of confectioners’ sugar makes it ideal for use in icings, whipped creams, and as a dusting on baked goods.

The starch added to confectioners’ sugar absorbs moisture, which helps maintain its powdery consistency. Cornstarch is the most commonly used starch in confectioners’ sugar, but other starches like tapioca or potato starch can also be used. The presence of starch contributes to the smooth texture and helps to prevent the sugar from caking, ensuring that it mixes well with other ingredients in recipes.

How much cornstarch is typically in confectioners’ sugar?

Generally, confectioners’ sugar contains about 3% to 5% cornstarch by weight. This small addition helps to prevent clumping and ensures easy handling during baking. The majority of the mixture, however, is pure powdered sugar, which provides the sweetness needed in recipes.

While this percentage may seem minimal, it plays a significant role in maintaining the quality of confectioners’ sugar. The starch absorbs moisture in the air, which helps to preserve the texture and keeps the sugar from forming hard lumps, making it particularly useful in humid environments.

Why is cornstarch added to confectioners’ sugar?

Cornstarch is added to confectioners’ sugar primarily to prevent clumping. When exposed to moisture, sugar can easily form hard clumps that are difficult to break up. By incorporating a small amount of cornstarch, manufacturers ensure that the sugar remains free-flowing and easy to measure and mix.

In addition to preventing clumping, cornstarch also enhances the texture of various recipes. It provides a smooth and velvety mouthfeel when used in frostings and creams, which is particularly desirable for baked goods that require a delicate and visually appealing finish.
