You don’t want to include the weight of your bowl in your measurements, so either zero out the scale (usually done with a button on a digital scale or a knob under the tray on a mechanical scale) or write down the tare (bowl) weight.
Grate carrots and radish, thinly slice green onions, grate ginger and mince garlic, placing everything, along with the red pepper flakes or Korean red pepper, in your bowl. NOTE: If you're concerned about the "hot" nature of the red pepper on your bare hands, either wear gloves or quickly mix it in right before packing your jar.
Discard the dirty or limp outer leaves of your cabbage, setting aside one of the cleaner leaves for use during the SUBMERGE step.
Quarter, then slice cabbage crosswise into thin ribbons. I leave the core in because I find it helps to hold the layers of cabbage together making the slicing job easier.
Add sliced cabbage to your bowl until the weight of your vegetables and cabbage is 1¾ pounds (28 ounces, 800 grams).
Sprinkle vegetables and cabbage with 1 tablespoon of salt and mix well.
Then, massage the vegetables with strong hands until moist, creating the brine. You should be able to tilt the bowl to the side and see a good-sized puddle of brine, about 2–3 inches in diameter. This process can take anywhere from 2 to 5 minutes. Notice how the mixture has shrunk. Due to the hot nature of the red pepper, wash hands wells after.
Grab handfuls of the salty, juicy cabbage mixture and pack them into your quart-sized (liter) wide-mouth canning jar, periodically pressing the mixture down tightly with your fist or a large spoon so that the brine rises above the top of the mixture and no air pockets remain.
Be sure to leave at least 1 inch of space between the top of the cabbage and the top of the jar. Because we weighed out just the right amount of cabbage to fit in your jar, this should happen automatically.
Pour any brine left in your mixing bowl into the jar and scrape out any loose bits stuck to the sides of the bowl or to the sides of your jar.
Take that cabbage leaf you saved during the SETUP step, tear it down to just fit in the jar, and place it on the surface of the packed cabbage. Forgot to save a cabbage leaf? No problem. You can fold a narrow piece of parchment paper to size or even cut an old plastic lid to size.
Place the 4-ounce jelly jar (or preferred weight) on top of the cabbage leaf, right side up with its lid removed. (Here I'm using the weight included with the Ferment'n fermentation lid.)
Lightly (to allow for escape of CO2 gases), screw on the white plastic storage lid or airlock of your choice, following their directions.
I like to label my jars using green or blue painter’s tape and a permanent marker. I note the flavor of sauerkraut I made and the date I started fermenting.
For this recipe, I used the Ferment'n water-sealed fermentation lid. It comes with a weight, the water trough you hold in place with a metal canning band and the lid.
Place your jar of fermenting sauerkraut in a shallow bowl (to catch the brine that may leak out during the first week of fermentation), out of direct sunlight. Wait for 1 week before opening to sample.

Should the brine level fall (very unlikely) and remain below the level of the sauerkraut during this first week,
dilute 1 Tbsp of salt in 2 cups of water
and pour some of this brine over the sauerkraut (removing the little jar first) until it just covers the mixture. Put the little jar back in, screw the lid on lightly and let the fermentation continue.
Don’t worry if the brine disappears after the 7- to 10-day mark. By this time, you’ve created a safe environment in which the bacteria that would cause mold or slime has been chased away by the beneficial bacteria produced during the fermentation process.
You can ferment your sauerkraut for up to 4 weeks. The longer you ferment it, the greater the number and variety of beneficial bacteria that can be produced.
Rinse off the outside of the jar. You can take the little jar out. Clean the rim if necessary (sometimes it can get sticky from the brine that overflows), and screw the lid back on tightly. Add to your label how long you fermented the contents.
Enjoy a forkful or two of your sauerkraut with your meals. It will continue to ferment – aging like a fine wine – but at a much slower rate than before. If the flavors are too intense, leave it the jar for a month or two and then eat it. You will be amazed at how the flavors have changed.
If successfully fermented (tastes and smells good), your sauerkraut can be kept preserved in your refrigerator for up to a year.
