"They're ... they're ... they're fanon!" I declared.

After we recovered, we explored this new analogy. The authentic places that serve any ethnic food the way you could find it in the source culture are canon. The things that everybody think of as being authentic, but you'd never find in the source culture, or you'd have not found it there five years ago, those are fanon. Things like french fries at a Chinese buffet? Those? Those are Mary Sues.
I think pre-made chocolate chip cookie dough is a Mary Sue on the field of American cookery to start with. To wrap that like a wonton and deep-fry it (given that I suspect deep-fried anything is a bit fanon when it comes to authentic Chinese cooking)? That's a Darth Mary Sue.
(And it's so good.)
