Bluebird Eggnog

Combine the cream, light rum, simple syrup, apple brandy, and the whole egg in a shaker.

Dry-shake the mixture vigorously to emulsify the egg.

Add ice to the shaker and hard-shake swiftly to chill the mixture.

Double-strain the cocktail into an Old Fashioned glass filled with light ice.

Garnish with a white chocolate eggshell placed delicately on top of the cocktail.
