How to Ferment Your Own Vegetables

We know that yogurt contains beneficial, “probiotic” bacteria that play a vital role in healthy digestion. But yogurt isn’t the only probiotic food out there.

All fermented foods contain beneficial living cultures. That goes for fermented vegetables like my beloved sauerkraut. Recently, we’ve been getting loads of cabbage in our weekly organic box, and I’ve been tempted to make kraut on my own, but didn’t know where to start.

Sandor Ellix Katz, aka Sandorkraut, wrote a book on vegetable ferments and has a website full of useful facts and recipes (including a recipe for sauerkraut!). This exerpt from her book describes how the basic process works:

The simple key to successful vegetable fermentation is to make sure your vegetables are submerged in liquid. That’s it, the big secret. Usually the liquid is salty water, also known as brine, but fermentation can be done without salt, or with other liquids, such as wine or whey. Typically, when fresh vegetables are chopped or grated in preparation for fermentation—which creates greater surface area—salting pulls out the vegetable juices via osmosis, and pounding or tamping the vegetables breaks down cell walls to further release juices, so no additional water is required. However, if the vegetables have lost moisture during long storage, occasionally some water is needed; if brine hasn’t risen to submerge the weighted vegetables by the following day, add a little water. In the case of vegetables left whole (cabbage heads, cucumbers, green tomatoes, string beans, okra, zucchini, eggplant, peppers—try anything), the vegetables should be submerged in brine.

Pretty much any vegetable can be fermented. Use what is abundantly available and be bold in your experimentation. Seaweeds are a wonderful addition to ferments, as are fruits, though mostly fruit ferments go through their process very quickly. I’ve even made delicious sauerkraut with mashed potatoes layered in with the salted cabbage, as well as kimchi with sticky rice layers. The sharp fermented starches are delicious. The spicing of vegetable ferments is quite varied, too. Kimchi typically includes red chili peppers, garlic, ginger, and scallions. Sauerkraut might include caraway seeds (my favorite), juniper berries, apples, or cranberries. New York–style sour pickles are spiced with dill, garlic, and sometimes hot peppers. To keep cucumbers crunchy, add to the brine some grape leaves or leaves of horseradish, oak, currant, or cherry.
