. . . As for the history of Watergate Salad, most folks think it has something to do with the Watergate Scandal which burst forth during the Nixon Administration in the mid-70s. The real origin of the name, however, is a bit more obscure and sketchy.
The dish was created by Kraft Corporate Affairs in 1975, the same year that pistachio pudding arrived on store shelves. Not even the Kraft company can substantiate the origin of the name “Watergate Salad" . . .
