Prepare Your Shaker: Add the blood orange juice, vodka, simple syrup, and egg white to a cocktail shaker.

Dry Shake: Shake vigorously without ice for about 15 seconds to froth the egg white.

Add Ice: Open the shaker, add ice, and shake again for another 15-20 seconds until well-chilled.

Strain and Serve: Double strain the mixture into a chilled coupe or rocks glass.

Garnish: Add a few dashes of orange bitters on top and garnish with a slice of dehydrated blood orange.
