Here's a google search that may help you get started. That said, just getting the words onto paper will be the hardest, longest portion of the work.
I would also suggest reading some non-fiction books for ideas of how you can layout your ideas.
"Group Theory in the Bedroom" for instance uses essays with postscripts/afterwords for each chapter. Each 'chapter' is it's own, self-contained work. You could yank out any chapter and have a cohesive work.
Meanwhile, "Guns, Germs, and Steel" breaks down more by topic/question and ties them together for a summary "the whole is greater than the parts" ending. You cannot take out a portion and still get the whole idea. They all intertwine.
Then you have biographies of all sorts that basically start with "So and so was born" and tell the story from there. You can yank out a portion and get a cohesive idea about "so and so's" high school years or education, but not the entire person.
I'd suggest leaning towards a Guns, Germs, and Steel style if you can. Tying together how fried chicken carries across cultures, connects huge portions of the planet, and carries an huge amount of "cultural capital" in popular culture and real life would be huge.
Some examples you can borrow/develop:
Last words: You're looking at the phenomenon of Fried Chicken, so sociological concepts like Phenomenonology and other Sociological terms will help you in the research phase of your question. Cultural rifts about fried chicken and "the right" way to make it for example will likely be discussed using terms like "cultural lag" and "norms".
