Fermented foods are a huge part of food preservation, a bigger part that most of us know. I think sometimes we underestimate fermenting as a means of keeping things alive because it doesn’t hold foods entirely in seeming stasis as canning or freezing do (yes, canned and frozen foods degrade too), which is what many of us really want. But what fermented foods do really well is work with the seasons to keep food cyclically – they are the ultimate preservers gift for people who want to be regularly engaged with their dinner.
Sandor Katz’s new book The Art of Fermenation is astonishingly comprehensive and fascinating. Besides the incredible history, recipes, cool pics of the microorganisms you are playing with, ideas for experimentation and socio-culture of food, there is Katz’s basic manifesto – we are not better off, safer, healthier or happier when we hand off the tools of food production and preservation to others.
