Convert granulated sugar to powdered sugar?

Ingredients:

- 1 cup granulated sugar

Instructions:

1. Place the granulated sugar in a blender or food processor.

2. Cover and blend on high speed for several minutes until the sugar is completely pulverized and resembles the texture of powdered sugar.

3. Sift the powdered sugar through a fine-mesh sieve to remove any larger crystals.

4. Store the powdered sugar in an airtight container at room temperature.

Note:

- Using a blender or food processor with a powerful motor is recommended for best results.

- If you don't have a blender or food processor, you can also use a mortar and pestle to grind the granulated sugar into a powder, but it will require more effort and time.

- Adding a small amount of cornstarch (about 1 tablespoon per cup of granulated sugar) can help prevent the powdered sugar from caking.

- Homemade powdered sugar may not be as fine as commercially-produced powdered sugar, but it is a suitable substitute for most baking and cooking purposes.
