Tips and Tricks
LIMES. Finding good, juice, and properly ripened limes are key for making great key lime cookies.
POWDERED SUGAR. Did you know that powdered sugar, confectioner’s sugar, and icing sugar all the same thing?
I don’t have powdered sugar. can I use regular sugar instead?
For this recipe, you need powdered sugar. But what happens if you don’t have any powdered sugar in your pantry. Don’t panic.
You can easily make your own powdered sugar!
How To Make Powdered Sugar
Use a high-speed blender like the Nutribullet or a small food processor. Combine one cup of cane sugar with 1 teaspoon of cornstarch and blend until the sugar dissolves into a fine powder.
Add a small amount of cornstarch (tapioca or potato starch works, too) to prevent the sugar from clumping.
