When I was at the University of Chicago in the 70s, the Hillel house sponsored these annual debates between two professors who were basing their arguments based on their disciplines. I even volunteered my professor once..
I think that it expanded to other places and also required remote viewing since the small room was no longer enough to accommodate all the attendees.
I think much was talked about the "significance" - economic, poetic, etc.
The only thing that I remember - because it was my professor - was about the blood generated from grating all those potatoes. I don't remember, though, whether this was an added "ingredient," since blood is a no-no in Jewish diet.
