Add the juice to a medium saucepan.
Sprinkle the gelatin over the top and allow to sit for a few minutes.
Turn the heat on medium-low and whisk the gelatin into the juice.
Once the gelatin is completely dissolved, remove from heat.
If using, add your fruit extract and honey/maple syrup and mix well.
Pour your mixture into silicone molds. I like to first pour my mixture into a pyrex liquid measuring cup because it has a nice lip on it for pouring, but you could also ladle your mixture into the molds.
Allow the molds to set up in the fridge for at least an hour.
Remove from the molds and store in an airtight container in the fridge for up to a week (if they last that long!)
