This is my basic recipe for making gelatin. Sometimes I let it dry out to make a sheet, sometimes I combine it with corn syrup to make flexible sheets. It's very versatile.
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 15 seconds if needed to melt fully
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
You can now use this base recipe by combining with metallics, food colors, corn syrup or whatever you need. Store leftovers covered in a container in the fridge.
