Dry Shake: In a cocktail shaker, combine the whiskey, lemon juice, simple syrup, pomegranate juice, and egg white. Shake vigorously without ice for about 15-20 seconds. This helps to emulsify the egg white, giving the cocktail a nice frothy texture.

Wet Shake: Add ice to the shaker and shake again for another 15-20 seconds until well-chilled.

Strain and Serve: Strain the cocktail into a chilled coupe or rocks glass.

Garnish: Optionally, garnish with a few pomegranate seeds or a lemon twist.

Enjoy: Serve immediately and enjoy your refreshing Pomegranate Whiskey Sour.
