I learned of this book from Jonathan Yardley's review in the Washington Post. We were out of ideas for our son's Spring Break and we hit on New Orleans: an eating vacation with Sara Roahen as our guide. I studied the book on a stationery bicycle as I tried to lose 15 pounds to get into shape for six great meals at Commander's Palace, Herbsaint, Bayona, Palace Cafe, Antoine's, and Galatoire's (listed in order, from greatest to merely great). Plus a few po' boys, lesser meals, and snacks, constrained only by our appetites.
This is a delightful and worthy book. It is organized around New Orleans' principal food groups with chapters on gumbo, red beans and rice, po' boys, etc. For each Roahen researched vintage cookbooks to trace origins, variations, and controversies. She uses this framework to interweave stories of her life in New Orleans and her experiences with the food and the people who make it, eat it, and live by it. She is a good writer, and her book served my purpose well. Every meal tasted better because of the context she provided.
That said her "menu-item framework" is awkward for the story she is telling. The book needs introductory chapters to describe New Orleans cuisine today, its evolution, and why it is unique (and superior!)
The introduction should follow easily from her careful research, but she doesn't even take up the fundamental distinction between Cajun and Creole until a chapter about poisson meuniere amandine, 159 pages into the book. The introduction should lay out the basic taxonomy of New Orleans food purveyors from the traditional five star restaurants, through contemporary innovators, to cafes and po' boy shops and street vendors. It would be a logical place for some of the personal vignettes of people who influenced her life in New Orleans which are awkwardly shoe-horned into chapters about food (e.g., the restaurant critic, Tom Fitzmorris in le boeuf gras) with which they have only a passing association.
Finally, I question her choice of menu items. There is a boring chapter on Vietnamese cuisine and another on a Mardi Gras coconut-trinket that I would gladly have traded for some missing chapters on traditional New Orleans cuisine: jambalaya, bread pudding, hot sauce. What is New Orleans without Tabasco?
