Asour is a traditional family of mixed drinks. Sours belong to one of the old families of original cocktails and are described by Jerry Thomas in his 1862 book How to Mix Drinks.[1]
It was popular during the 1940s, and Kevin Starr includes it in "an array of drinks (the gin sour, the whiskey sour, the gin Rickey, the Tom Collins, the pink lady, the old fashioned) that now seem period pieces, evocative of another era".[1]
The classic pisco sour recipe contains pisco brandy (usually an un-aged grape brandy from Perú), fresh lime juice, fresh lemon juice, simple syrup, egg white, and bitters.[3] It is shaken, strained, and served straight in a cocktail glass then garnished with the bitters (cinnamon can be used). The addition of egg white creates a foamy head when shaken before serving.[4] While pisco sour is flavoured with key lime by default, pisco is combined with other fruit to create mango sour, maracuya (passion fruit) sour, lucuma sour and so forth.[5] Peru has a National Pisco Sour Day (which lasts a weekend) in mid-February,[6] and Chile has Pisco Day in mid-May.
The basic Daiquiri, sometimes called a Daiquiri sour, is made with rum, lime juice and simple syrup.[7] One account of the drink's origin is that the general manager of the Spanish-American Iron Core Company, which operated the "Daiquiri" mine, ran out of gin one night when making gin sour for his guests, and switched to rum. This rum sour became known as the Daiquiri. However, earlier printed recipes for rum sour exist such as one from Jerry Thomas from 1887.[8]
The whiskey sour is a mixed drink containing bourbon whiskeyorrye whiskey, lemon juice, sugar, and optionally a dash of egg white to make it a Boston Sour. It is shaken and served either straight or over ice. The traditional garnish is half an orange slice and a maraschino cherry. If floated with claret red wine it's called a New York sour.[9]
A notable variant of the whiskey sour is the Ward 8, which often is based with either bourbon or rye whiskey, both lemon and orange juices, and grenadine syrup as the sweetener. The egg white sometimes employed in other whiskey sours is generally not included in this variation.
