How to Preserve Foods and Our Food Culture: Wild Fermentation
In this day and age of highly processed, artificial ingredient-infested “food products”, fermentation offers a beautifully simple, healthy, and delicious alternative to preserving some of our favorite foods. Fermentation is a natural food preservation process typically requiring nothing more than very simple ingredients and time. Many popular, everyday foods would not exist without magical fermentation processes: sauerkraut, cheese, yogurt, miso, soy sauce, beer, and wine, just to name a few.
Fermentation not only preserves food, it makes food more nutritious and digestible, and the practice has spanned thousands of years. (Just one example: over 1000 years ago, Icelandic Vikings transformed milk cultured with rennet into skyr, a kind of thick yogurt-like cheese for later consumption.) It is a transformation made possible by bacteria and fungi. (I like to call it “controlled rotting”). For example: Salt some cabbage and throw it in a crock in the corner of your kitchen, and within a few weeks you’ll have delicious, aromatic sauerkraut, the result of a magical lactic acid fermentation.
