Instructions
Prepare the Watermelon: Carefully slice the top off the mini watermelon. Reserve this cut piece. Place the watermelon (cut side up) into a sturdy bowl to help keep it balanced and steady during the filling process.
Scoop Out Flesh: Using an ice cream scoop or a large spoon, carefully scoop out the red flesh from the watermelon, leaving about ½ to ¾ inch of the white rind intact around the edges. Be gentle to avoid piercing the rind.
Make Watermelon Juice: Put the scooped watermelon flesh into your blender. Blend on high for 10-15 seconds until smooth. Double-strain the juice through a fine-mesh sieve (and a cheesecloth if you have one) into a separate bowl to remove any pulp or seeds. Measure out 1 ½ cups of this fresh watermelon juice.
Bloom the Gelatin: In a large bowl, whisk together the 4 packs of unflavored gelatin with the ½ cup cold water and 1 ½ cups strained watermelon juice. Whisk thoroughly to ensure the gelatin is evenly distributed and “blooms” (softens and swells).
Dissolve Gelatin: Quickly whisk in the 1 ½ cups of boiling water with the bloomed gelatin mixture until the gelatin is completely dissolved and no granules remain. Set the mixture aside and allow it to cool to room temperature. It’s crucial for it to be cool, not hot, when adding fruit.
Add Fruit to Watermelon: Place your prepared fruits – strawberries, blueberries, blackberries, red grapes, and green grapes – directly into the hollowed-out watermelon bowl. Gently shake the watermelon a few times to help the fruit distribute evenly.
Fill with Gelatin Mixture: Carefully pour the cooled gelatin mixture into the fruit-filled watermelon bowl until it reaches the top.
Chill & Set: Place the reserved cut-off top back onto the watermelon (it doesn’t need to seal, just cover). Carefully transfer the entire watermelon to the refrigerator. Allow it to set for at least 5 hours, or ideally, overnight, until the Jello is firm.
