1 mini seedless watermelon (about 5 pounds)
Two 3-ounce boxes watermelon-flavored gelatin, such as Jell-O
Three 0.25-ounce packets unflavored gelatin (from one 1-ounce box)
1 teaspoon granulated citric acid
1 cup (8 ounces) vodka
If you would like to make this recipe kid friendly, omit the vodka and replace it with 1 cup of the excess watermelon juice.
