Pre-chill a coupe glass in the freezer or with ice water.
Prepare the cinnamon-sugar rim: combine 1 teaspoon ground cinnamon with 60ml (½ cup) white granulated sugar on a small flat plate. Moisten the outer edge of the glass rim with a cut lemon wedge, then dip and rotate into the cinnamon-sugar mixture to coat evenly. Set aside.
Cut a coin-sized disc of orange peel for garnish and set aside.
Add 45ml Chairman's Reserve Spiced Rum, 22.5ml Ferrand Dry Curaçao, 30ml fresh lemon juice, 10ml rich sugar syrup, and 10ml egg white into a cocktail shaker.
Perform a dry shake (without ice) for 10–12 seconds to emulsify the egg white and build foam.
Add a large scoop of ice to the shaker and shake vigorously for a further 12–15 seconds until well chilled.
Double strain through a Hawthorne strainer and a fine mesh strainer into the prepared coupe glass.
Express the oils from the orange peel coin over the surface of the drink, then rest it skin-side up on the foam as garnish.
The reverse dry-shake technique - shaking without ice first, then with ice - produces a denser, more stable foam than the traditional method. It's the key to getting that signature velvety texture that defines a well-made Cable Car.
