Add the pickle juice to a pot and sprinkle over the gelatin. Allow to sit for 5 minutes to harden.
Transfer to the stove and heat on medium-low for 2-3 minutes until the mixture returns to liquid. Remove from the heat. Slightly skim the top to remove any bubbles or foam from the vinegar.
Use a dropper to transfer the gummy mixture into a mold of your choice (like this). Alternatively, you can pour it into a glass container.
Allow to set in the fridge for a few hours or overnight before carefully removing. Store in the fridge.
