It’s officially summertime now, which means it’s time to whip up some refreshing drafts. This one's currently enjoying heavy rotation at chez frenchman and me. The recipe is for one cocktail, but can easily be scaled up, if you’re serving a whole slew of people. If you can’t find key limes, sub 1/2 a small, regular lime. If you can’t find ginger syrup, you can make your own with fresh ginger, water and sugar. (Fine, fine you could also just sub a dash of ginger ale.) —Cristina Sciarra
Toss the watermelon into a blender or food processor, and blitz for a minute or two. After that you, you can run the juice through a sieve (which will ensure you have a smooth watermelon juice), or leave it a little chunky.
Juice one of the key limes into the watermelon juice. Give it a little stir. Slice the other, thinly and crosswise, and set it aside.
Empty some ice into a cocktail shaker. Pour the ginger syrup and the rum directly over the ice. Add the watermelon-key lime juice. Attach the cap, and give the cocktail a brisk shake, until the metal feels quite cold to the touch.
Pour the drink out into a glass, making sure to leave the ice behind. Garnish with the remaining key lime, and enjoy cold.
