Edible glitter is easy to make and can usually made with ingredients already in your bakery! Make a little or make a lot to add some sparkle to your edible treats.
Pour water into a shallow dish. sprinkle gelatin evenly over the water and let it absorb for 5 minutes
Microwave for 30 seconds, then stir and microwave for another 5 seconds if needed to melt fully. You can tell it's melted when you can't see any grains of gelatin anymore.
Let sit for 5 minutes and bubbles will rise to the surface and create a white foam. Skim this foam off the surface with a spoon and discard
Add metallic dust to the melted gelatin and stir
Pour gelatin onto a large sheet of plastic wrap and use a pastry brush to smooth it out and holes that develop. As the gelatin cools it will be easier to smooth. Don't worry if it's not perfect, we're going to grind it up anyway
Let the gelatin dry overnight. It might start peeling up on it's own or you may have to peel it up from the plastic to release it.
Break it up or cut it into pieces.
Place into a spice grinder or coffee grinder or even a food processor until it is very fine.
