Ice type

  • Cubed (for shaking), Large Cube (for serving if in a rocks glass)

Mixing equipments

You will need a cocktail shaker to combine the ingredients, a jigger for measuring, and a strainer to pour the finished drink. A citrus juicer is essential for preparing the fresh lemon juice.
  • Cocktail shaker for mixing and chilling.
  • Jigger or measuring tool for accurate proportions.
  • Strainer (Hawthorne and Fine-mesh) for a smooth pour.
  • Citrus juicer for fresh lemon juice.

Instructions

The key steps involve a dry shake without ice to build foam, followed by a wet shake with ice to chill and dilute. Double straining is crucial for a perfectly smooth texture.
1. Chill your chosen glass (coupe or rocks) by filling it with ice or placing it in the freezer.
2. Add Gentleman Jack whiskey, fresh lemon juice, simple syrup, orange liqueur, and egg white (if using) to a cocktail shaker.
3. Perform a 'dry shake': seal the shaker without ice and shake vigorously for 15-20 seconds to emulsify the egg white and create foam.
4. Add a generous amount of cubed ice to the shaker, seal it again, and perform a 'wet shake': shake hard for another 10-15 seconds until the outside of the shaker is well-chilled.
5. Discard the ice from your chilled glass. Double strain the cocktail through a Hawthorne strainer and a fine-mesh strainer into the glass to ensure a silky smooth texture.
6. Let the foam settle for a moment. Garnish by adding a few dashes of Angostura bitters onto the foam and/or expressing a lemon peel over the drink.
7. Serve immediately and enjoy.

Garnishing

A classic garnish is a lemon peel expressed over the drink to release its aromatic oils. If using egg white, a few dashes of Angostura bitters on the foam is both visually appealing and aromatic.
  • Lemon Peel: Express the oils over the drink and drop it in.
  • Brandied Cherry: A single cherry dropped into the glass.
  • Bitters Art: Drop bitters onto the foam and drag a cocktail pick through them to create a pattern.
