Your Essential Food Books?

For those of you with a cooking/food writing/food science collection, what’s indispensable? What do you currently find yourself returning to again and again?

For me, Nikki Segnit’s “Flavor Thesaurus: A Compendium’ and Flavor Thesaurus: More Flavors are both in there, along with The Noma Guide to Fermentation, Koji Alchemy, and *Burma: Rivers of Flavor.” Oh, and Sercarz’s *Spice Companion."

For food writing, I’m always happy to dip into some M.F.K. Fisher.
