A liqueur coffee is a coffee drink with a shot of liqueur. It may be served in a special liqueur coffee glass, often with cream and sugar. Liqueur coffee are all variants on what is widely known as Irish coffee, hot coffee with whiskey and a layer of cream (not whipped) floated on top. Liqueur coffee is particularly popular in Galicia, Spain, where it is considered a traditional drink. Widely known throughout Spain as carajillo, it is made from a blend of coffee, sugar, and strong alcohol such as aguardiente, orujo, or rum.
