Cut the watermelon in half lengthwise with a sharp knife for a clean, stable base.

Scoop the flesh into small, round balls using a melon baller or spoon. Place them in a large bowl.

In a saucepan, combine rum, Jolly Rancher candies, sugar, and water. Heat over low to medium, stirring often, until the candies dissolve completely (about 5–7 minutes).

Remove from heat and let the mixture cool for a few minutes.

Pour the cooled Jolly Rancher rum mixture over the watermelon balls, ensuring they’re fully submerged.

Cover and refrigerate for at least 4 hours—or overnight for the most flavor!

Drain the watermelon bites on paper towels before serving.

Arrange on a platter and garnish with fresh mint leaves for a pop of color.
