The history of this delicious concoction is not as old as one would think, and unsurprisingly, a bit controversial. Whether the birthplace was the flying boat terminal at Foynes Airport or Shannon Airport as the Buena Vista plaque indicates, bartenders Joe Sheridan and Jack Koeppler were instrumental in spreading this iconic drink. You can learn a little more here. If you are in America though, don't expect too many establishments to know how to make this drink properly. Do some research and find a good recipe. The ingredients are simple: preheated glass, sugar, good coffee, Irish whiskey (I prefer Jameson), and plain whipping cream.
