Cathy, given your proclivities (we all know you're a spicy wench) you might also want to check out Andreas Viestad"s "Where Flavor Was Born." To my mind, the best cookbook published in 2007.
Viestad explores the cuisines of the Indian Ocean, using, as his starting point, the fact that there's a similarity of the spices used, but different cuisines. Many of those spices are the same basic flavors as used in the Mid-east.
It's arranged like "Spice," in that the chapters are dedicated to individual spices. And his text is nothing short of incredible. Here's a sample. He's describing Stone Town, in Zanzibar, and says:
"And it is all about secrets and semi-secrets, about what is hidden and what lies in the open, about the lies that serve noble causes and truths that can hurt. There are rumors and gossip, more so than other places, one should think.....In the space between truths and lies, between what is public and what is secret, everything happens."
For those like you and me, who read cookbooks like others read novels, that's pretty heady stuff.
One to avoid, on the other hand, is Amy Riolo's "Arabian Delights: Recipes & Princely Entertaining Ideas from the Arabian Peninsula." In my opinion it contributes nothing to the literature on the subject except bulk.
