The whiskey sour cocktail is a perfect balance of sweet, sour, and warmth from the bourbon, creating one of the most satisfying cocktails. It's a simple drink that anyone can master, but the right technique makes all the difference.
Add whiskey, fresh lemon juice, simple syrup, and egg white (if using) to a cocktail shaker.
Fill the shaker with ice and shake vigorously for about 15 seconds to emulsify the egg white. This is known as a "wet shake."
Strain the mixture into a clean glass, discarding the ice.
Pour the liquid back into the shaker and shake again without ice (a "dry shake") for about 15 seconds to create a smooth, frothy texture. Strain into a rocks glass over fresh ice. Garnish with a lemon twist or cherry.
Notes
The method of using the wet shake and then a dry shake is to help get the beautiful foam on top of the glass if using egg whites.
If you prefer to avoid the egg white but still want the foam, fee foam is a good alternative.
