Eggnog, Morgenthaler

Beat the whole eggs in a blender on medium speed for a minute.

Gradually incorporate the superfine sugar and blend for another minute.

With the blender still running, add freshly grated nutmeg, brandy, spiced rum, whole milk, and heavy cream until well combined.

Chill the mixture thoroughly to allow the flavors to meld.

Serve in a chilled cocktail coupe, grating additional nutmeg on top just before serving.
