In a medium-sized bowl, mix three tablespoons of gelatin powder with a cup of cold water. Then, allow it to soak or bloom for about 10 to 15 minutes. After that, wait until the gelatin powder absorbs all the water in the bowl.
Afterward, take a saucepan. Then, heat 3 cups of water and 2 cups of sugar. After that, add a teaspoon of citric acid over the stove. Next, stir the mixture occasionally using a spoon. Doing this dissolves all the ingredients in the saucepan.
Next, take the saucepan away from the heat when you begin to observe vapor appearing above the mixture. And please do not let the mixture reach the boiling point.
After that, add the soaked or bloomed gelatin to the mixture. Remember to stir until the gelatin dissolves completely without any clumps in the mixture.
When the gelatin completely dissolves, add the colorless flavoring that you desire.
Then, let the mixture cool inside the saucepan for about 1 to 2 hours at room temperature. Do this till the foam disappears from the surface, and the mixture becomes clear.
Afterward, pour the mixture into the silicone mold that you have chosen. Then, remove the air bubbles.
After that, place the molds inside the refrigerator. And let the gelatin set overnight.
Lastly, once the gelatin is stable, you can serve and enjoy it!
