Ireland
Irish coffee is Irish whiskey, dissolved sugar and strong hot coffee under lightly whipped cream, drunk unstirred. The Foynes original; why the sugar matters.
Irish coffee was created at Foynes flying-boat terminal in County Limerick in the 1940s, for cold and miserable transatlantic passengers.
Warm the glass first. Dissolve the sugar completely in the coffee and whiskey before floating the cream.
It is structural. Dissolved sugar increases the density of the coffee below, which is what allows the cream to float rather than sink.
Skip the sugar and the cream mixes in, giving you a milky whiskey coffee — pleasant, and not an Irish coffee.
Lightly whipped — thickened but still pourable, poured over the back of a warm spoon. Stiffly whipped cream sits as a lump; unwhipped cream sinks.
Through the cream, unstirred. Hot sweet whiskey coffee arriving through cold cream is the entire point.
Germany’s Pharisäer uses rum and predates it by decades. Austria’s Fiaker is an Einspänner with rum. Spain’s carajillo is the espresso version.
Many countries arrived at the same idea independently.
The chef usually credited at Foynes is Joe Sheridan. In 1952 a travel writer, Stanton Delaplane, brought the drink to the Buena Vista Cafe in San Francisco, which worked out how to float the cream reliably and made it famous in the US; the bar still serves it in large numbers. The traditional glass is a stemmed, tulip-shaped glass of about 6 oz (180 ml), which keeps the layers visible.
The equipment this actually requires — not a shopping list, the shortest route to doing it properly.
1.25 L · 92–96 °C (198 to 205 °F) brew · copper element · SCA certified
Hits proper brew temperature in about four minutes and holds it, which is the entire job and which almost no cheap drip machine does. Hand-built in the Netherlands, repairable indefinitely, and priced accordingly.
Best for: A household that drinks filter coffee by the pot, every day, for years.
Double-walled borosilicate that keeps a drink hot and the outside cool, and shows the layers of a latte. Cheap enough to replace when one inevitably goes.
Best for: Espresso-based milk drinks, and anyone who likes seeing them.
