Jeffrey Morgenthaler's Eggnog

Select a Toddy glass for serving.

Prepare a garnish of freshly grated nutmeg to top the cocktail.

Blend the egg on medium speed for one minute.

Gradually add the superfine sugar while continuing to blend for another minute.

Continue blending as you incorporate the cognac, spiced rum, milk, and double cream.

Refrigerate the mixture for several hours to ensure it is well chilled.

Serve the eggnog in the chilled Toddy glasses.

Dust each serving with the grated nutmeg garnish.
