Can you make pure icing sugar?

You can't make "pure" icing sugar in the sense of creating it from scratch. Icing sugar, also known as powdered sugar, is simply finely ground granulated sugar. Here's why:

* It's a Processing Technique: The "magic" of icing sugar is the grinding process. Granulated sugar is pulverized into a fine powder, and often cornstarch is added to prevent clumping.

* No Chemical Changes: No new chemicals are introduced during the process. It's simply a physical change in the form of the sugar crystals.

What you *can* do:

* Buy it pre-made: The easiest option is to buy powdered sugar at the grocery store.

* Grind your own: If you're feeling adventurous, you can grind granulated sugar in a food processor or blender. Be careful to avoid overheating the sugar, as this can cause it to clump.
