Chill the Glassware: Place a coupe or martini glass in the freezer for at least ten minutes before you begin to keep the cocktail frosty.
Combine the Liquids: Pour 2 oz of London Dry Gin and 1 oz of lime cordial directly into your cocktail shaker.
Add Ice: Fill the shaker generously with large, dense ice cubes to ensure rapid chilling without over-dilution.
Shake Vigorously: Seal the shaker tightly and shake hard for 12 to 15 seconds until the outside of the tin becomes frosty.
Strain and Serve: Double strain the liquid through a Hawthorne strainer and a fine mesh strainer into your chilled glass to catch any small ice shards.
Garnish: Float a thin, pre-chilled lime wheel on the surface of the drink and serve immediately.
