Even if drinking vinegar sounds like a dare—and maybe that's why you ordered it—it's anything but. It's sweet and sour and icy-cold. It vibrates and clangs with fruit and vinegar, and soothes with sweetness and mint. It is the most refreshing drink you will have this summer. And because it's a grown-up drink without alcohol, you can take it on a picnic, at any park, without having to look side-eyed at cops that might pass by.

Sliced watermelon, sliced unwaxed cucumber, and spearmint, for garnish
Bring the 3 cups water and the salt to a boil in a medium saucepan. Add the honey, stir to dissolve, and remove from the heat.
Combine the watermelon and mint in a large bowl. Stir in the honey-water and let cool to room temperature, then add the vinegar. Steep the mixture in the refrigerator for several hours or up to overnight.
Strain the mixture and eat the watermelon chunks, if desired. Pour the concentrate into a clean glass jar, and store in the refrigerator for up to 1 week.
To serve, pour 1/4 cup of the concentrate into a glass over ice and dilute with 3/4 cup water. Garnish with the watermelon, cucumber, and mint.
