Been sitting on my shelves for a while; when the library turned up an audio copy, I thought it would be a good time to give it a first read.

Covers the impact of salt through history, touching on science towards the end. I learned a lot about the Basques, Celts, and the names of towns in Europe. The recipes didn't add much, in my opinion. Other people have complained about a lack of references; I'll have to dig up my paper copy to check that. A decent book, a pinch more than 3 stars.
