This simple, refreshing cocktail from San Francisco bartender Erick Castro mixes Beefeater 24 gin, fresh lime juice, mint, and soda water for a perfect warm-weather libation.
Muddle all of the ingredients (except for the soda water) together in a shaker. Fill with ice and shake aggressively. Strain and pour into a highball glass. Top with soda water and garnish with fresh mint leaves.
