Whisk gelatin (2 tbsp if wanting more jello like, and 3 tbsp if wanting a little more firm fruit snack like) with 1/4 cup juice in a small bowl. -After a few minutes it will thicken into a gelatin bloom
Heat remaining juice & strained raspberry puree or sweetener over stove top over medium heat
Once heated, whisk in gelatin bloom
Add a few drops of your green colorant & water mixture until your desired green shade is achieved
Pour into your brain molds
Set in the fridge for an hour, then loosen the edges and they'll pop right out
Use a toothpick dipped in chocolate to draw on eyes
Enjoy!
Keep in the fridge if not eating right away
