Well, I've mentioned here in another thread (I think) about the Little House series. The descriptions of food in those just make me drool.
So simple but so interesting.
Also, the Clan of the Cave Bear books, especially from the second book on, have some really cool descriptions of foods and cooking methods that intrigue me and have encouraged me to consider different flavour combinations.
I've gotten, but not read yet, a book called Mina which is supposed to be set in a kitchen in a manor house or something (I can't remember specifically). It's supposed to have neat food stuff.
