Fermenting is an old-fashioned food preservation method that uses salt, brine, time, and natural fermentation to change flavor and help preserve foods. Fermented foods can include sauerkraut, dill pickles, kimchi, relishes, and other vegetables.
Fermenting is different from regular vinegar pickling. In fermentation, the food changes over time as acidity increases. That is why it is important to use trusted instructions, clean containers, proper salt amounts, and safe storage.
