Some of the jazz players were hungry after a gig, early morning, bar couldn’t serve so the cook made up some chicken and waffles...the rest is as they say history
FYI...Chop Suey would have been better example, as it IS an American dish; something NEVER made nor even eaten in any part of China.
And American Goulash isn't goulash at all, misnamed, and no Hungarian, nor anyone of Hungarian heritage/someone who like Hungarian food, would touch with a barge pole!
Danish pastry isn't Danish at all, but an Hungarian pasty, renamed during WW I, in America, because nonHungarians were boycotting anything and everything even remotely connected to those on the side we were fighting.
So yes, there absolutely ARE purely American "culture" icons solely ours alone!
