I had an egg white in the fridge to use up, so logically I made sprinkles. Right? I did a riff on what appears to be the most popular sprinkle recipe in the the food blogging world, Brave Tart. I'm guessing her version followed exactly is better than my version, so I'm not going to post my recipe. They are good and pass my 2-year-old taste tester's inspection, but if I were to go through the effort of piping them all over again, I'd want an outstanding version.
