1 Tbsp. gelatin
2.5 Tbsp. water
Mix gelatin and water and let soak for 5 minutes.
Melt the soaked gelatin in a microwave oven for 10 seconds.
Take the gelatin out of the microwave and check if it is completely melted and clear.
If the gelatin has not melted completely, stir it and return it into the oven for another 10 seconds.
Once the gelatin is melted, stir in the desired color.
Keep the mixture warm or keep reheating it as it thickens up while you are working.
