According to sources, the first Irish coffee was invented and named by Joe Sheridan, head chef at the restaurant and coffee shop in the Foynes terminal building. (A precursor to Shannon Airport, Foynes was the last port of call for seaplanes on the eastern shore of the Atlantic. During Word War II it would become one of the biggest civilian airports in Europe) The coffee was conceived after a group of American passengers disembarked from a Pan Am flying boat one miserable winter evening in the 1940s. Sheridan added whiskey to the coffee to warm them. After the passengers asked if they were being served Brazilian coffee, Sheridan told them it was Irish coffee and the name stuck. In 1951, Stanton Delaplane, a travel writer for the San Francisco Chronicle, tasted what had by then become the traditional airport welcome drink and was smitten. Returning home he told his friend Jack Koeppler, owner of the Buena Vista Café and the two set about trying to recreate the drink. Stymied by the Irish flair for floating the cream on top, the duo went so far as to seek help from the city’s then mayor, George Christopher, who also happened to own a dairy. He suggested that cream aged for at least 48 hours would be more apt to float, and so it did. In later years, after the Buena Vista had served, by its count, more than 30 million of the drinks, Delaplane and the owners claimed to grow tired of the drink. (And who can blame them, the currency had been cheapened: bastardized versions of a drink that were less hot toddy and more like hot candy had popped up everywhere.) A snark after my own heart commented that the problem with Irish coffee is that it ruins three good drinks – coffee, cream, and whiskey – but you’d never surmise that from the crowds that still take the Hyde Street cable car to Maritime Park in search of the original elixir. In fact, if you’ve never tasted a proper Irish coffee, you have no idea what you are missing – two go down nicely on an afternoon, while three guarantee a lovely start to the evening. Here’s how it’s done: Fill a glass goblet with hot water, then empty. Pour in hot coffee until about three-quarters full. Drop in two sugar cubes. Stir. Add a full jigger of whiskey and top with a collar of lightly whipped cream. Do not stir. Drink piping hot in two or three sips. Okay, four at most.
