Chapter 3 Further Reading — Salt

A reading list organized by depth. Pick by where you are.

Beginner

Samin Nosrat, Salt, Fat, Acid, Heat (Simon & Schuster, 2017). Nosrat's book is the single best non-technical introduction to salt's role in cooking. The first quarter of the book is entirely about salt — when, where, how much, why. Especially valuable for the home cook who wants to internalize "season at every layer" without the molecular biology.

Mark Kurlansky, Salt: A World History (Walker, 2002). A trade-history book about salt as commodity, currency, and political force. The Roman salarium, the French gabelle, the Hallstatt mines, the Sahara salt routes, Gandhi's salt march, the salt cod trade — Kurlansky covers them all in accessible prose. Read it for the cultural context this chapter gestured toward.

J. Kenji López-Alt, "The Food Lab: Brining and Salting" (Serious Eats, multiple articles, 2010–2020). López-Alt's accumulated articles on brining, dry-brining, and salting timing are the best free resource on salt-and-meat chemistry. Search "Kenji López-Alt brining" for the canonical pieces. He runs the experiments and reports them with rigor and warmth.

Intermediate

Harold McGee, On Food and Cooking: The Science and Lore of the Kitchen (Scribner, revised ed. 2004). Chapter 5 ("The Cook as Chemist") and parts of Chapter 6 ("A Brief History of Foods and Their Cooking") cover salt's chemistry and history. McGee is the foundational reference for the technically curious home cook and the food-science student. Density of information is high; readability remains good.

Ina Lipkowitz, Words to Eat By (St. Martin's, 2011). Particularly the chapter on salt — the etymology, the cultural references, the ways salt has shaped language and commerce. A bridge between Kurlansky's history and the more technical food-chemistry literature.

Sandor Ellix Katz, The Art of Fermentation (Chelsea Green, 2012). Katz's encyclopedic guide to fermentation includes detailed discussion of salt's role in lacto-fermentation across many cultural traditions. The kimchi, sauerkraut, miso, gundruk, and salt-brined olive sections are particularly relevant to Chapter 3 readers heading toward Chapter 33.

Modernist Cuisine: The Art and Science of Cooking, Volume 3, "Animals and Plants" (Myhrvold, Young, Bilet, 2011). The brining and curing sections in Volume 3 give the modernist treatment of salt's role in meat chemistry, with extensive citations to the food-science literature. Expensive, but library copies are usually available.

Advanced

Peter Belitz, Werner Grosch, and Peter Schieberle, Food Chemistry (5th ed., Springer, 2009). The graduate-level food chemistry textbook. Chapter 8 ("Minerals") and the protein chemistry chapters cover the molecular basis of salt's interactions with food matrices in detail. For the food-science student or science teacher who wants the formal treatment.

O. Fennema, S. Damodaran, K. Parkin (eds.), Fennema's Food Chemistry (5th ed., CRC Press, 2017). The other standard graduate-level text. Particularly strong on water activity, ionic strength, and the physical chemistry of preservation. Chapter 2 (on water and aqueous solutions) and Chapter 18 (on food preservation) are most directly relevant.

Andrew Mente, Martin O'Donnell, et al., "Associations of urinary sodium excretion with cardiovascular events in individuals with and without hypertension: a pooled analysis of data from four studies" (The Lancet, 2016, 388:465-475). A widely cited analysis from the PURE study and follow-up data, arguing that the relationship between sodium intake and cardiovascular outcomes is more complicated than population-level low-sodium recommendations suggest. Reading this alongside the AHA's standard guidelines gives a sense of the active scientific debate. (The AHA position can be found in their published "Dietary Sodium and Cardiovascular Disease Risk" statements.)

Patricia Cleveland, et al., "Salt and the kidney: a complex connection" (Kidney International Reports, 2021). A review article connecting sodium intake, water activity, and kidney function. Useful for understanding the population-health argument with its complications.

International Commission on Microbiological Specifications for Foods (ICMSF), Microorganisms in Foods 6: Microbial Ecology of Food Commodities (2nd ed., Springer, 2005). Cured meat (Chapter 4), fermented vegetables (Chapter 16), and the relationship between water activity and microbial growth are covered with the empirical specificity needed to design a safe ferment or cure. Reference text for serious home curers and food-science students.

Web and audio resources

Helen Rennie, "Why I'm Using Diamond Crystal Salt" (YouTube). A clear, short video explaining the kosher-salt-brand problem and its consequences for cooking. Good for visual learners and a quick share with friends.

Joe Hanson, "What Salt Does to Your Brain" (PBS Be Smart, YouTube). Short, well-produced video on the biology of salt taste and craving. Especially good for the science-teacher audience preparing demonstrations for high-school students.

Gastropod podcast, "The World's Most Dangerous Spice (and Other Salty Stories)" (2018). A conversational hour on salt's chemistry, history, and contemporary politics. Cynthia Graber and Nicola Twilley are reliable narrators of food-science topics.

The Salt Network (saltnetwork.com). A trade-and-research site for the salt industry that occasionally publishes useful articles on regional salts, mineralogy, and applications. Especially useful for tracking down information on specific traditional salts (cheonilyeom, fleur de sel, etc.) that don't appear in mainstream cookbooks.

A note on the cooking-and-chemistry literature

Cooking writes about salt frequently. The food-chemistry literature writes about NaCl rarely (it's so foundational that monographs assume it). The bridging literature — McGee, López-Alt, Modernist Cuisine — is where most readers will find the chemistry made directly applicable to the kitchen. If you find yourself wanting more depth than this chapter, the place to go next is McGee's On Food and Cooking, which is roughly twice the depth of this chapter at twice the page count. From McGee, the trail leads naturally into Belitz or Fennema for the formal physical chemistry. The journey from cooking salt to dissolving salt to ionic-strength calculations is one of the cleanest applications of physical chemistry to everyday life — a journey worth taking.
