While this classic warmer gets top billing around St. Patrick’s Day, it’s a welcome after-dinner treat on almost any occasion. Because the recipe is so elemental, it pays to use the best coffee and cream you can find—you will be able to taste the difference. Whip the cream softly so it sits in the glass in soft peaks. And as for that shot of whiskey? Any blended Irish whiskey—like Tullamore DEW, Redbreast, or the classic, Jameson—should do the trick nicely.
