1. What is Flour Sugar?
Flour sugar (Icing Sugar), also known as powdered sugar, is a spice used in cooking, especially in sweet pastries. Recognizable by its fine, white texture, this sugar doesn't clump, and when added to water, it dissolves quickly. Its distinctive feature is its smooth, white appearance. When used, you'll notice it doesn't clump, and if you drop it into water, it dissolves faster than the small-grained sugar we commonly use.
Current Types of Flour Sugar in the Market
- Refined flour sugar is processed from pure natural sugar that has been finely ground. If unused, it tends to clump, but a gentle squeeze will restore it to its original state.
- In addition to finely ground sugar, some other ingredients such as potato starch, cornstarch, etc., are added. These substances prevent the sugar from clumping and, importantly, do not affect the flavor of the flour.
