The cocktail was introduced to the public in 1974, devised by the importer of
Amaretto di Saronno as a simple mix of two parts amaretto liqueur to one part lemon juice. It became a popular cocktail in the 1980s; most bartenders at the time substituted commercial
sour mix for the lemon juice. The drink was popular as a one-dimensional easy-drinking cocktail, flavored mostly by the base spirit used.
Imbibe attributes this change to bartender
Jeffrey Morgenthaler, who published a new version of the drink in 2012 using cask-strength bourbon, rich simple syrup, and egg white. ==See also==
