Irish coffee is a warm beverage made by combining hot coffee, Irish whiskey, sugar, and a layer of cream on top. The drink is typically served in a glass to showcase its distinct layers. The sweetness of the sugar balances the bitterness of the coffee, while the cream adds a rich texture. This drink originated in Ireland in the 1940s, created by a chef to warm up travelers arriving at the Foynes airport. Over the years, Irish coffee has gained popularity worldwide, often enjoyed as a comforting treat or after-dinner drink.
