This is a great eggnog recipe for when you have a group of people with different ideas about how eggnog should be served, as they can always add equal parts brandy and rum to the beverage without ruining its great flavor. I have noticed that many people who say they do not care for eggnog, have only tried store bought eggnog…. This recipe by George Mahaffey , former chef of Aspen’s Little Nell Hotel, is always a holiday hit and perfect to serve after Christmas dinner. Use fresh grated nutmeg for best flavor. MAKE AHEAD: The eggnog can be refrigerated overnight. Stir before serving.
