Price check: 12.3 ounces of colored sugar = $10.00. 16oz of pure, white granulated sugar = $1.00.
Oh, but it's not colored, you say? Well, not yet.
Instructable-r StarshipMinivan offers an unbearably easy tutorial for creating your own colored sugar. And most likely, you already have everything you need in your pantry.
Just mix the food coloring into the sugar with a fork. Spread it out, allow to try, and break up the clumps.
