Of all the magnificent cookbooks I saw in New Orleans, this was the only one I felt like hauling back. (Probably just because I didn't feel like carrying much that day.) Its virtue is its simplicity -- no exhaustive attempt to give a sweeping overview of the region's food. Instead, it focuses on one thing alone: gumbo. There are 27 gumbo recipes with some general guidelines and comments. Sixty-three pages. That's it.
I haven't actually tried any of the recipes yet, but they look fairly doable. Whether or not they'll taste anything like some of the great gumbos I sampled in Louisiana is another matter.
