Melon balls were the quintessential summer party food when I was growing up, but it wasn't until I was out of college that I had my first melon ball "salad." My current favorite is this recipe that has a mojito-like splash over the melon. Dreamy!
Place the watermelon and cantaloupe balls in a baking dish in a single layer. In a bowl, whisk together the lime juice, rum and honey until combined. Pour the lime mixture over the melon balls and toss to coat. Add the mint leaves. Let sit for 2 to 3 hours in the fridge, flipping the balls once or twice if desired.
To serve, scoop the melon balls into a large bowl and pour the rum mixture over top. Cover with a sprinkling of fresh mint leaves.
