Pour 1/2 cup of the kombucha into a small saucepan.
Sprinkle the gelatin powder on top and whisk in with a fork or wire whisk.
Turn heat on low and heat just enough to dissolve the gelatin so now powder remains. I check this by rubbing a tiny amount between my fingers and making sure I don't feel any grit or remaining powder.
Remove from heat and pour into a medium size bowl.
Quickly whisk in the remaining kombucha.
Pour into a lightly greased 8x8 or 9x13 baking dish.
Place in refrigerator for 4 hours or overnight until completely set.
Serve and enjoy!
Notes
Make sure you're using carbonated kombucha for fun bubbles in your Jell-o!
