This idea is vaguely Irish, as if I knew anything about that, inspired by a cauliflower colcannon at Whole Foods around St Patty's day.
I suppose you could add some boiled potato if you were inclined toward authenticity, but it does not start with the letter "C".
The main idea is that the creamed corn substitutes nicely for the traditional dairy cream.
