  • 2 cups fresh watermelon, diced
  • 1/2 cup fresh squeezed lime juice (about 4-6 limes)
  • 3 tbsp honey
  • 3-4 tbsp unflavored gelatin*


  • Place watermelon in a blender or food processer, and turn on for a few seconds until it’s all liquid. Place a fine mesh strainer over a bowl, and pour the watermelon puree through. You’ll be left with about 1 cup of watermelon juice in the bowl that you’ll use for this recipe. You can discard the pulp in the strainer (or save it for use in baked goods).
  • Place watermelon juice in a medium pot over low heat. Add lime juice and honey. Continue to heat on low, whisking a few times, until everything is combined and hot (do not boil).
  • Whisk in gelatin and remove from heat. Continue whisking for another 30 seconds. If there are any chunks of gelatin remaining, just scoop them out.
  • Use a dropper to place the mixture in silicone molds. Pop in the freezer for about 15 minutes (or in the refrigerator for an hour), then enjoy! To store, keep in the fridge for up to 4 days.



  • If you prefer softer, squishier gummies – use 3 tbsp of gelatin. If you prefer more solid, springy gummies – use 3.5-4 tbsp gelatin.
  • This recipe makes around 45-50 of the large gummies (the star-shaped ones).  If you're using smaller molds, you can expect more.
  • If you don’t have silicone molds, you can pour this in a rectangular dish and then cut out squares when it’s solid.
