What is the definition of icing sugar?

Confectioner’s sugar, also known as icing sugar, is finely powdered granulated sugar that contains cornflour to absorb moisture and prevent clumping.

What is the distinction between powdered sugar and icing sugar?

The primary distinction between the two is the inclusion of cornflour in the latter. Powdered sugar is essentially finely powdered granulated sugar. However, icing sugar contains a specific amount of cornflour mixed in.

How can I make icing sugar?

To prepare this mixture, use a dry blender and add equal parts sugar and cornflour. For every 1 cup of sugar, add 1 tablespoon of cornflour. Blend until the mixture is finely ground, but be cautious not to overheat the blender. If the blender gets too hot, the mixture will become moist. Strain the mixture through a fine sieve to remove any remaining chunks. It is now ready to use.

What is the duration of storage?

If stored properly, this can be kept at room temperature for 3 months. Refrigerate it to prolong its shelf life for up to 6 months.

What alternative can I use instead of cornflour?

You can substitute cornstarch for cornflour. If you do not have either, rice flour can also be used.
