Tailor was kind enough to share this recipe for the lovely and magical Pimm's Pony which, you may recall, cured my ills at the kickoff reception for Tales of the Cocktail.
1 Kirby cucumber, coarsely chopped
2 ounces Hendrick's gin
1 ounce Pimm's
1 ounce lemon-lime soda
Puree the cucumber in a blender. Strain the puree through a fine sieve, pressing to extract as much juice as possible. Transfer the juice to a jar with a tight-fitting lid.
In a cocktail shaker, combine the gin and Pimm's. Add ice and shake for 20 seconds. Strain the drink into a tall glass over ice and top with the soda. Vigorously shake the cucumber juice for 30 seconds. Spoon some of the foam onto the drink and serve right away.
