Step 1

Before you do anything else, place 2 coupe or martini or old-fashioned glasses or whatever stemware you've got in the freezer.

Step 2

Add the bourbon, rum, ice cream, cinnamon, and nutmeg to the shaker and shake vigorously for 10 seconds. (If you don’t have a cocktail shaker, you can blitz everything in a blender.)

Step 3

Divvy the creamy eggnog concoction between the chilled glasses. If you want, add a pinch cinnamon or nutmeg for garnish. Serve the eggnog without delay.
