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.
Interesting to read about the world history from the view of creating, transporting and trading salt. In our modern age, it is a common relatively uninteresting commodity, but in days prior to refrigeration salt was the primary (or only) means of preserving food and thus a critical commodity to civilizations.
It is more a history book than a story book which makes it a bit dry and slow going at times, but overall a good world history book from Romans, to Marco Polo, to American and French Revolutions to India.
