What is fermentation?
Fermentation can be a tricky thing to explain.
In science, we refer to fermentation as metabolism without oxygen or anaerobic metabolism.
Before the convenience of refrigeration and industrialized food, fermentation was even more widespread as an invaluable tool for creating unique flavors and preserving the bounty.
In the culinary realm, we can think of fermentation as the transformation of food by microbes. This process is vast and present in more types of food than you might realize.
