Add 1 teaspoon of brown sugar and a good measure of Irish whiskey into the warmed glass.
Step Three
Fill the mug to within 1 centimeter of the brim with hot, strong black coffee. Stir well to dissolve all the brown sugar. Step Four
Carefully pour lightly whipped cream over the back of a spoon so that it floats on top of the coffee.
Step Five
Do not stir after adding the cream; optimal flavor comes from drinking the coffee and Irish whiskey through the cream.
