All you need is cabbage, salt, and time.
It’s amazing to watch simple, pure ingredients transform through fermentation. Crisp, sweet cabbage wilts down into something delightfully tangy, its cell walls softening under the power of salt. At its very essence, sauerkraut is pickled cabbage. The word “pickle” tends to get attached to vinegar-brined vegetables, but it really refers to any vegetable preserved in brine — whether that brine is vinegar or salt. The difference with a salt ferment is that the vegetables create their own brine as they break down, developing rich, complex flavors and a natural dose of probiotics, vitamins, and enzymes along the way.
For the most basic sauerkraut, all you need is cabbage, salt, and time. That’s it — no added water, no starter culture. Salting and massaging the cabbage pulls out its own juices, which become the brine it ferments in. Once you have the basic method down, you can get creative with different spices, fruits, and vegetables to make it your own. Start simple and get familiar with the flavor that develops naturally — more often than not, keeping it simple is best. Caraway seeds are the classic add-in and a great place to start, but there’s plenty of room to experiment with layers of spice, sweetness, and other vegetables that bring their own texture.
Cabbage is especially well-suited to fermentation. It naturally carries the lactic acid bacteria that drive the process, and its high water and sugar content give those bacteria plenty to feed on. You don’t have to add those microbes — you just create the right environment (salt, no oxygen, and a little time) and let them do the rest.

Fermentation is the process by which bacteria and yeast consume sugars, digest them, and transform them into byproducts such as alcohol, organic acids, and gases. Although there are many different forms of fermentation, the one taking place in this recipe is lacto-fermentation. Lacto-fermentation is performed by a group of bacteria called lactic acid bacteria (LAB). These little guys produce lactic acid and are most famous for making cheese and yogurt due to their ability to break down lactose, a.k.a. milk sugar.
With sauerkraut there’s no added water — salting and massaging the cabbage draws out its own juices, which become the brine it ferments in. The one exception: if your cabbage is on the dry side, or you just want more liquid to work with, you can move to a larger jar and top it off with a 2% salt brine — it won’t compromise the fermentation. LAB is already present on all plant matter, which is what lets vegetables ferment without any added starter culture. This process also creates enzymes and vitamins that make nutrients more bio-available in your body. Lacto-fermentation has been around as long as humans have been preserving food, and it’s the reason we have classics in global cuisines like sauerkraut, kimchi, sourdough, and so much more.
