I made homemade gummies for the first time last night after I got my gelatin and silicone mold from Amazon.
The kids loved them. The adults loved them. And they give you a vehicle for the gelatin, which has all sorts of health benefits they say. Bonus! :)
The recipe I used calls for watermelon juice but friends have confirmed you can use any juice. I fresh-squeezed oranges for my first batch. I know someone who buys Odwalla Juice from Whole Foods and uses that.
Because the original recipe has links to everything you need (like the gelatin) plus really great photos, I'm just going to link to that for you:

I like the easy Paleo stuff.
