Measure and add the fruit juice and honey to a small saucepan on the stovetop. Whisk to combine, then bring the mixture to a light simmer over medium heat.
After it has begun to simmer, remove the saucepan from the heat. Slowly and evenly sprinkle the gelatin into the juice mixture, whisking thoroughly.
Whisk in any optional add-ins, as well.
Once fully blended, use a dropper to fill the gummy bear molds with the liquid mixture. Place the molds carefully into the refrigerator or freezer for about 30 minutes or until firm.
Pop the gummies out of the molds and enjoy! Store leftovers in the refrigerator for up to a week.
Notes
Sprinkle the gelatin over the juice mixture rather than dumping it in all at once.
Avoid juices like papaya, pineapple, kiwi, or mango, as they contain an enzyme that can prevent the gelatin from setting up.
Add a squeeze of lemon juice to add some tartness.
If you don't want to use honey, you should be able to substitute maple syrup or cane sugar.
Fill the silicone molds fully for the best results.
When transferring the gummy mixture to the refrigerator, I like to set my molds on a cookie sheet or similar tray just in case I slosh them.
