Of all the drinks to come from this country, this is the only one known simply as “The Irish Cocktail”, so you know it’s good. This recipe first appeared in the 1888 edition, of Harry Johnson’s Bartenders’ Manual, which means it’s got plenty of years’ experience behind it.
As after-dinner cocktails go, the whiskey sour is one of the most famous, and for good reason. By mixing Irish whiskey and lemon juice with egg white and sloe berry bitters, you get a delicious classic cocktail that has really stood the test of time.
