Method: Muddle the sour cherries in a shaker, and add remaining ingredients and ice. Shake and strain into an ice-filled Collins glass. Top with soda. Garnish with a sour cherry and a lime wedge or wheel. Salute Monsieur Ricky, last seen in a boa and heels on the Champs-Élysées.
Variation: Make it a Pretty Ricky Silver Fizz by removing the ice and adding an egg white to the shake.
