I know, that's a pretty subjective statement so let's just say that Eating India: An Odyssey into the Food and Culture of the Land of Spices is easily the best food writing I've read in a very, very long time. I thought I was going to read this one cover to cover in no time, but I forced myself to savor it like good chocolate. I rationed it out, a chapter at a time, going back for seconds and thirds as often as I pleased.
My knowledge of Indian cooking is so much greater after reading Eating India. Sure, we all know about the Mughal influenced North Indian specialties, but this book takes the reader on a comprehensive tour of numerous Indian communities starting in the author's own Calcutta and wandering all over the subcontinent. No recipes, but lots of interesting tidbits to chew on.
