Make Your Own Caster Sugar

If your recipe calls for caster sugar, you can make it with granulated sugar in just minutes. The process is simple: Simply add a cup of granulated sugar to your food processor, coffee grinder, or blender and whirl it for a few minutes.

Then, mix in 1 tablespoon of lemon juice or white vinegar. This will help caster sugar dissolve more quickly and incorporate into sauces, puddings, and bases.
