Don’t let the name distract you; this old-timer is about as soothing as electrically heated bunny slippers and not nearly so silly looking. It can also be served cold—just shake everything up with a little cracked ice (and, of course, don’t bother heating the milk).
1 ounce cognac
1/2 ounce dark, full-bodied rum
1 teaspoon rich simple syrup
4 ounces (give or take an ounce) hot milk
To finish: freshly grated nutmeg
Combine the cognac, rum, and simple syrup in a mug, top off with milk, and grate nutmeg over the top.
