Create a double boiler: using a small saucepan, fill with about an inch of water and place a metal or glass bowl on top (not touching the water). Pour the water into the bowl. With spoon ready and already stirring, add the gelatin. Stir until it becomes thickened and slightly lighter in color.
Let sit for 5 minutes. This is so the gelatin absorbed the water and hydrates.
Turn stove on medium. Stirring as the granules start to dissolve. When the granules are fully dissolved you are ready to go. You may see tiny bubbles, don't be confused. If you aren't sure, put a little between your fingers and feel for any left over granules. It is EXTREMELY easy to over-heat your gelatin, which will ruin it. Do not over boil. Take it a very little at a time.
Take bowl off heat and let it sit for 5 minutes. This will allow the white foam to come to the surface and separate, allowing us to "clarify" our gelatin.
Skim the white foam off the top of the gelatin and discard it.
Pour the glycerin mixture into the gelatin. Mix until smooth.
It's ready to start using! See notes for special instructions!
