Step 1: Prepare the Honey Syrup – In a small bowl or jar, mix equal parts honey and warm water. Stir until the honey fully dissolves. This creates a smooth syrup that blends seamlessly into the cocktail.
Step 2: Chill the Glass – Place your serving glass in the freezer or fill it with ice water while you prepare the cocktail to ensure a perfectly chilled drink.
Step 3: Mix the Ingredients – In a cocktail shaker, combine the whiskey, fresh lemon juice, honey syrup, and sea salt. If using an egg white, add it now for a silky, frothy texture.
Step 4: Dry Shake – If using an egg white, first shake the mixture without ice for about 10 seconds to create a creamy, frothy consistency.
Step 5: Add Ice and Shake Again – Add a handful of ice to the shaker and shake vigorously for another 15-20 seconds until well chilled.
Step 6: Strain – Remove the ice from your serving glass and strain the cocktail into it. If using egg white, the froth should form a creamy layer on top.
Step 7: Garnish and Serve – Sprinkle a tiny pinch of sea salt over the top, add a lemon wheel or twist for a decorative touch, and, if desired, finish with a few drops of bitters.
