Add the pickle juice to a pot and sprinkle over the gelatin. Allow to sit for 5 minutes to harden.
For a milder flavor, use 1/2 cup pickle juice and 1/2 cup water.
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 carefuly removing. Store in the fridge.
These gummies are great post-workout or for some quick electrolytes. Keep in mind that they are high in sodium and vinegar. I recommend having just a few at a time.
Notes
To get 1 cup of pickle juice, I strain a jar of pickles like grillos, or any other pickles that you like! If you prefer to balance the pickle flavor, use 1/2 cup water and 1/2 cup pickle juice for a milder flavor.
