I've got Claudia Roden's book, The Food of Spain, and it's a fascinating read. She explains her theory in it. Like all her books, they aren't simply recipes books, there is so much history, observation and culture in there as well. I heartily recommend it, the photography alone in it is beautiful. Plus it has a great recipe for a staple of my Camino, Galician empanada. Her other book on Middle Eastern cookery is a fantastic reference as well.
