If you look at the list of the top wheat importers for 2010, almost half of them are Middle Eastern regimes: Egypt, Algeria, Iraq, Morocco, Yemen, Saudi Arabia, Libya, and Tunisia. Egypt is the number-one importer of wheat in the entire world. Tunisia leads the entire world in per capita wheat consumption. So it's no wonder that the revolutions began with Tunisians waving baguettes in the streets and Egyptians wearing helmets made of bread.

There hasn't been a lot written about it in the Western media. But in the Arab world, and Western Asia as a whole, Baghdad was always known as a famously bookish, intellectual city. There's an old saying that Cairo writes, Beirut publishes, and Baghdad reads.

Which is one of the dangers of immersion journalism: you can find yourself getting sucked into battles you have nothing to do with, in this case an ongoing battle between Muslims.

You [can] become part of someone else's narrative. Every once in a while I would get people asking me questions like, "If your husband is a Muslim, then why haven't you converted to Islam?" Interestingly enough, almost every person who asked me that was a Sunni, and it was their not-so-subtle way of implying that my Shiite husband was a bad Muslim for letting his infidel wife run around unconverted.

So much of what we see and hear about the Middle East focuses on what we call politics, which is essentially ideology. But when it comes to the Middle East, and especially the Arab world, simply depicting people as human beings is the most political thing you can do. And that's why I chose to write about food: food is inherently political, but it's also an essential part of people's real lives. It's where the public and private spheres connect.

Pedro Teixeira, the great Portuguese merchant-adventurer, wrote a beautiful description of a coffeehouse with windows overlooking the Tigris and the ruins of old Baghdad. That was in 1604, and he's visiting the same street that I write about in the book, named after Abu Nuwas, though it wasn't called that back then.

Rulers like Egypt's Gamal Abdel Nasser started subsidizing bread as a way to buy loyalty, or at least obedience, and this system became so pervasive that the Tunisian scholar Larbi Sadiki described countries who used it as dimuqratiyyat al-khubz - "democracies of bread." But the problem with this system of offering bread in exchange for genuine democracy is that it can never last - sooner or later, the bread will run out, and people will start demanding bread and roses too.
