Can you mix flour and sugar to make powder sugar?

Here's why:

* Texture: Flour has a different texture than powdered sugar. Flour is made of larger starch granules, giving it a grainy texture. Powdered sugar has been finely ground, giving it a smooth, powdery consistency.

* Sweetness: While flour does have some sweetness, it's much less sweet than sugar. Powdered sugar is made from granulated sugar that has been pulverized, so it retains its sweetness.

* Purpose: Flour and powdered sugar have different culinary purposes. Flour is used for thickening, binding, and providing structure to baked goods. Powdered sugar is primarily used for sweetening and dusting.

To make powdered sugar, you need to:

1. Grind granulated sugar: Use a food processor or blender to grind granulated sugar until it's fine and powdery.

2. Add cornstarch: This helps prevent the powdered sugar from clumping.

If you're looking for a substitute for powdered sugar, you can use a combination of granulated sugar and cornstarch in a 1:1 ratio. However, the result won't be exactly the same as commercially-produced powdered sugar.
