The Galactic Gourmet
by James White
A correspondent mentioned the idea of culinary science fiction, and this seemed such a surprising concept that I went looking for precedents in the superb Encyclopedia of Science Fiction.
This is a charming, if simple, book about a great cook who decides to join Sector General, the great galactic hospital, in order to do something about the food. All the usual challenges of hospital food are present, along with such inter-species challenges as table manners in a cafeteria where the physician sitting next to you might look a lot like your dinner.
