Salt

14½ hours of facts about salt and salt-adjacent things. Iodized salt. Potassium chloride. Mahatma Gandhi's Salt Campaign. Soy sauce. Catsup. Cheshire. San Francisco Bay. Oil exploration. The Dead Sea. The book never dwells too long, and everything is surprisingly, for me at least, interesting.

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.
