How to: Fermenting Foods – The Joy of Fermentation

Fermenting Foods How to ferment

For a few thousand years now, people have been fermenting foods. Many of the foods — even the highly processed ones — we all (guiltily) enjoy are fermented: Chocolate, soy sauce, coffee, olives and many, many more.

And while the process may seem mysterious, it is actually quite simple. Raw fermentation, the process in which many foods are transformed from regular vegetable to tangy, delightful fermented foods — think sauerkraut and kimchi — are easy, safe and incredibly healthy.

Health benefits of fermented foods

Fermenting foods requires taking food, in this particular case, vegetables, adding salt and allowing naturally occurring lactic acid bacteria to partially digest the starches in the food transforming them and preserving them.

In the process, the microbes that facilitate the transformation make the food easier to digest, create antioxidants and release vitamins and minerals.

The microbes that grow in the food are also healthy for the digestive system (think yogurt, another fermented food). The microbes in the human digestive system like fermented food. Fermented foods have been shown to restore stomach acid pH and were also used as a traditional treatment for ulcers.


Quite simply, the fermented vegetables we tried had at best, three ingredients — salt, water and vegetables.

We used mason jars, although some home fermenters have used plastic mayonnaise containers or any jar they have lying around the house. Some people even use 5 gallon buckets covered with cloth.

The food then ferments in the jars (or other containers) over a manner of days or weeks.

Once the process is finished (a matter of taste more than anything, some people prefer their food strongly flavored while others prefer theirs milder) the food is packed into jars and refrigerated, halting the fermentation process by causing the microbial activity to go dormant.

During the fermenting process, gas is produced.

The gas must be released, but exposing the material to air limits the fermentation process.

Many home fermenters “burp” their jars by opening the jars allowing the gas to escape and closing them.

If you have more than a few jars, however, this process gets time consuming — and quite frankly, annoying — really fast.

That’s why we use Fermentools products.

Their air locks come with special lids, allowing gas to escape and limiting the air exposure to the

product. They’re also sturdy enough for multiple uses, which means after we’re done with this batch, we can wash them and use them all over again. Fermentools also sells Himalayan salt.

The great thing about fermenting your own food is you can use additions like Himalayan salt to increase the mineral content of your food.

It’s an easy way to add healthy trace minerals to your diet.

  • 1 head cabbage (about 2 pounds)
  • 1/4 cup sea salt or kosher salt
  • Water
  • 1 tablespoon grated garlic
  • 1 teaspoon grated ginger
  • 1 teaspoon sugar
  • 8 oz korean radish
  • sliced scallions to taste


  • Grate the cabbage separately (or slice. We prefer grating because it exposes more surface area, aiding in the fermentation process).
  • Leave the garlic, ginger and sugar separate for now.
  • Salt the cabbage and massage it, until it softens and produces heavy amounts of juice.
  • Cover the cabbage with water. Place a cloth over the bowl and let it sit for about 2 hours.
  • Rinse the cabbage three times and set it aside.
  • Take the garlic, ginger and sugar and add water, making it into a paste.
  • Combine all the vegetables, draining any excess juice, and add the paste.
  • Add red pepper to taste.
  • Pack the kimchi into jars and allow it to ferment for several days (we ferment ours on the kitchen counter and keep it out of direct sunlight).
  • Cap with an air lock or burp the kimchee as needed.
  • Taste it as it ferments to find out how strong you want it. Once it gets to the right spot for you, then change the lid on the jars and put it in the fridge.
  • Repeat the process often as possible to keep yourself in kimchi. You’ll thank us.
