I don’t really dedicate much of my blogging to what I do these days, my college teaching work. I guess that I kick up enough dust talking about my Mount Vernon years, my Humanities years, my Carnegie Mellon years, and my former jobs and bosses as it is.

But this is a fairly positive post (mostly, anyway). It about something that I learned recently while teaching one of my World History courses. Something so simple that it’s amazing sometimes how stupid I can be.

I realized one day in discussing the age of exploitation, um, well, exploration that one of the best ways to think about this period — heck, any period in world history, really — begins and ends with one word: food. I’d taught this course a couple of times for University of Maryland University College already. Not to mention having served as a teaching assistant under the great Peter Stearns while a grad student at Carnegie Mellon a decade and a half before (see my “Ego Inflation” post from last month).

But on that fall evening in ’09, looking at exploration patterns, commerce patterns and the state of the world circa 1600 CE, it hit me how I could just about reorganize every aspect of the way I’d been teaching World History by just looking at how much food has influenced it. Every bite we take, everything we imbibe, has some history attached to it, and with it, stories of bloody conflict, imperial conquest or rare attempts at true humanity and cooperation.

This is about much more than Jared Diamond’s books on the rise and fall of civilizations because of resources and the lack thereof. Commodities like salt, sugar, black pepper and olive oil have all been written about over the past fifteen years. It’s fairly obvious that these spices and other foodstuffs were fundamental in the histories of the Middle East, ancient Greece and Rome, India, Timbuktu and Western Europe over the past 5,000 years.

Still, I’m not really talking about that kind of history, either. It’s more about something as simple as taking a modern dish and using its ingredients to tell a story. Take something like a chocolate cake with vanilla icing. If the ingredients are natural and not ones cooked up at a chemical plant in northern New Jersey, then they’ve come from all over the world. Cocoa, the main ingredient to mix with the flour, is from the cacao plant, which originally from South America, but is primarily produced in sub-Saharan Africa. Sugar’s needed to sweeten it, and though originally from India, has been grown in Florida, Louisiana and in the Caribbean for centuries. One of the main economic drivers for the enslavement of Africans was the European need to rot out their teeth with the stuff.

Vanilla extract or vanilla beans are originally from Mexico and other parts of Central America. But the largest producers of it are Indonesia and especially Madagascar. There’s history in every gram of devil’s food cake with vanilla icing that we eat.

You could do the same thing with a “traditional” Chinese stir-fry. Especially if ingredients like baby corn or

sweet and sour sauce are added to the mix. That’s because baby corn and tomatoes (the latter the main ingredient in sweet and sour sauce) are both from the Americas, not Asia or Europe. Both arrived in Ming China nearly 500 years ago.

Every dish, whether invented in 2011 CE or 2011 BCE, has a rich story attached to it. From that story, we can all find important patterns in world history, cultural development, domination and destruction within. It may not be the most profound thing I’ve ever stumbled upon. Still, I didn’t get this from Peter Stearns or Jared Diamond. If anything, I might’ve gotten this from Forrest Gump.
