A peculiar but beautifully balanced sour that splits its base evenly between blended Scotch and Irish whiskey, with lemon juice for brightness and almond-rich orgeat to round the edges. Shaken and served up and cold, it drinks smooth and nutty, the orgeat taming the whiskies' grain and smoke into something unexpectedly elegant.

The earliest printed recipe turns up in a 1922 volume by Harry MacElhone, "Harry of Ciro's ABC of Mixing Cocktails", which names no one as its inventor — MacElhone stands on record as the drink's first publisher, not its creator. Eight years later Harry Craddock included it in The Savoy Cocktail Book, again with no maker credited. Who first mixed it remains unknown, as does the identity of the Cameron in its name, and it is not among the IBA's official cocktails.
