Measure 2 ounces premium vodka, 0.75 ounces fresh lemon juice, 0.5 ounces simple syrup, and 0.5 ounces egg white into a cocktail shaker.

Dry shake the lemon juice, simple syrup, and egg white vigorously for 10 to 15 seconds until foamy.

Add 2 ounces chilled vodka to the shaker and stir gently with a bar spoon.

Fill the shaker with ice cubes until three-quarters full.

Shake vigorously for 10 to 15 seconds until the shaker is frosty on the outside.

Place a Hawthorne strainer on the shaker and hold a fine mesh strainer above your glass, then double strain into a chilled coupe or rocks glass.

Twist a lemon wheel or twist over the foam to express oils and drop it into the glass.
