Also have SALT ( the history of salt; it IS fascinating! ), FOOD IN HISTORY, IN THE DEVIL'S GARDEN (it's about once forbidden to eat foods ), and ones about what was eaten and recipes for dishes eaten in Ancient Rome and one on Ancient Greek dishes.
I always mean to read those books that tell the story of salt, etc. I never seem to get around to them. I usually end up with my usual obsession with British food - something Americans do not understand anymore than Brits understand the beauties of American cookery. Sadly, we just seem to hate each other...
