Warm the water in a small saucepan to 150°F (this helps the gelatin to dissolve)
Dissolve the gelatin. Just be aware that it’s going to get stringy and clump together. Don’t add more; just keep stirring, and it’ll eventually dissolve.
Once it’s dissolved, transfer it to an airtight container with the lid off to set it up in the fridge. This will take several hours.
Finally, secure the lid and store it in the fridge. Use it as needed!
Notes
