Ingredients

1/2 teaspoon finely grated lime zest plus 2 tablespoons juice (from 1 lime)

2 tablespoons light-brown sugar

2 tablespoons light rum

1/4 teaspoon salt

6-pound piece chilled seedless watermelon

2 tablespoons slivered fresh mint leaves

Preparation

In a large bowl, whisk together lime juice, sugar, rum, and salt.

Using a melon baller, scoop melon into balls (you’ll get about 10 cups), or cut melon into bite-size chunks. Add melon to lime mixture in bowl. Sprinkle with mint and lime zest, and toss gently to combine. Serve immediately, or cover and refrigerate, up to 2 hours.
