Korean Spicy Fermented Cabbage

Featured in: Fresh Everyday Bowls & Greens

Craft traditional Korean kimchi by salting napa cabbage for hours, then coating it in a vibrant spice paste of gochugaru, garlic, ginger, and fermented fish sauce. Pack vegetables into jars and let fermentation transform them into tangy, probiotic-rich perfection over several days. The result delivers spicy crunch and deep umami that enhances any meal.

My tiny apartment kitchen filled with the sharp, garlicky scent of fermentation for the first time when my Korean neighbor showed me her grandmother's technique. She insisted on weighing everything precisely, but laughed when I asked for exact measurements on the chili flakes. "Trust your nose," she said, handing me a jar that would change how I thought about preserving vegetables forever.

Last winter, I made a triple batch during a snowstorm when my refrigerator was already overflowing. The jars sat on my counter, bubbling away, while I worried I had committed to making enough kimchi to feed the entire neighborhood. Three weeks later, I was giving jars to everyone who crossed my doorstep, delighted by how something so simple could bring so much joy.

Ingredients

  • 1 large napa cabbage: The foundation of everything, so choose heads with tight, crisp leaves and no wilting
  • 80 g coarse sea salt: Do not use table salt as the iodine can interfere with fermentation
  • 1 medium daikon radish: Adds essential crunch and sweetness that balances the heat
  • 4 scallions: Their mild onion flavor develops beautifully during fermentation
  • 6 cloves garlic: Fresh garlic makes all the difference here, do not substitute powder
  • 3 tbsp Korean red chili flakes: Gochugaru has a unique flavor profile that regular chili flakes cannot match
  • 2 tbsp rice flour: Creates the traditional paste texture that helps the seasonings cling to every leaf

Prepare the cabbage:
Cut the napa cabbage lengthwise into quarters, then chop into 2-inch pieces that are easy to handle during salting and seasoning
Salt and soak:
Dissolve sea salt in 1.5 liters cold water in a large bowl, submerge the cabbage completely, and weight it down to keep it under the brine for 2 hours
Rinse thoroughly:
Wash the salted cabbage under cold water 2 to 3 times until the water runs clear, then drain it very well
Make the rice paste:
Whisk rice flour with 150 ml water in a small saucepan over medium heat until it thickens into a smooth porridge, then let it cool completely
Blend the seasonings:
Puree the cooled rice paste with garlic, ginger, onion, fish sauce or soy sauce, and sugar until completely smooth
Adjust the heat:
Stir in gochugaru gradually, starting with 3 tablespoons and adding more until you reach your preferred spice level
Combine everything:
Mix the drained cabbage with daikon radish, carrot, scallions, and the spice paste, using gloved hands to massage until every piece is coated
Pack the jars:
Press the kimchi firmly into clean glass jars, eliminating air pockets and leaving 1 inch of headspace at the top
Start fermentation:
Seal the jars and leave them at room temperature out of direct sunlight for 1 to 2 days, opening daily to release gas
Refrigerate and enjoy:
Once the kimchi tastes sour and tangy, move it to the refrigerator where it will continue developing flavor for weeks

My friend Sarah was skeptical when I handed her a jar of bubbling red cabbage. She took it home anyway, and three days later texted me at midnight saying she had eaten half the jar standing in her kitchen. Now she makes her own batch every month and claims it cured her winter colds.

Understanding Fermentation

Lactic acid bacteria are already present on cabbage leaves, and the salt creates an environment where they can thrive while harmful bacteria cannot. The transformation from raw vegetables to something complex and tangy never ceases to amaze me, no matter how many batches I make.

Serving Ideas Beyond the Side Dish

While kimchi is perfect alongside rice, try frying it with eggs for breakfast, adding to ramen bowls, or even topping a baked potato. The fermented flavor adds brightness to rich dishes and depth to simple ones.

Troubleshooting Your Ferment

If your kimchi smells off instead of tangy, something may have gone wrong with the salt ratio or cleanliness of your jars. White film on top is usually harmless kahm yeast, but fuzzy mold means you should start over.

  • Taste your kimchi at different stages to learn how you prefer it
  • Keep fermentation jars away from direct sunlight and heat sources
  • Always use clean utensils when removing kimchi to avoid contamination

There is something deeply satisfying about preserving food and watching it transform. Once you taste your first batch of homemade kimchi, you will understand why people have been making this for centuries.

Recipe FAQs

How long does kimchi fermentation take?

Fermentation requires 1-2 days at room temperature for initial sourness, though flavor develops deeper complexity over several weeks in cold storage.

Can I make kimchi vegan?

Replace fish sauce with soy sauce or vegan alternatives. The fermentation and umami remain excellent without animal products.

Why do I need to salt the cabbage first?

Salting draws moisture from cabbage leaves, creating the brine needed for fermentation while softening texture for better spice absorption.

What's the purpose of rice flour in the paste?

Rice flour thickens the spice mixture, helping it adhere evenly to vegetables while providing carbohydrates beneficial for fermentation bacteria.

How do I know when kimchi is ready to eat?

Taste after 48 hours. When sourness balances heat and vegetables maintain pleasant crunch, transfer to cold storage to slow fermentation.

What You Need

Produce

01 1 large napa cabbage (about 2.5 lbs), quartered lengthwise and cut into 2-inch pieces
02 1 medium daikon radish (about 7 oz), julienned
03 4 scallions, sliced into 2-inch lengths
04 1 medium carrot, julienned (optional)

Salt & Water

01 1/3 cup coarse sea salt
02 6 cups cold water

Spice Paste

01 6 cloves garlic, minced
02 1 thumb-sized piece fresh ginger, peeled and minced
03 1 small onion, roughly chopped
04 3 tbsp fish sauce or soy sauce for vegan version
05 1 tbsp sugar
06 3-5 tbsp Korean red chili flakes (gochugaru), adjusted to taste
07 2 tbsp rice flour
08 2/3 cup water

Steps

Step 01

Prepare the Cabbage: Cut the napa cabbage lengthwise into quarters, then chop into 2-inch pieces for even salting and fermentation.

Step 02

Salt the Cabbage: Dissolve coarse sea salt in 6 cups cold water in a large non-reactive bowl. Add cabbage pieces, tossing thoroughly to coat. Place a plate and weight on top to keep vegetables submerged. Let stand for 2 hours, tossing every 30 minutes to ensure even salting.

Step 03

Rinse and Drain: Rinse the salted cabbage thoroughly under cold water 2-3 times to remove excess salt. Drain well in a colander, allowing excess water to escape for about 15 minutes.

Step 04

Prepare Rice Paste Base: Whisk rice flour with 2/3 cup water in a small saucepan over medium heat, stirring constantly until thickened and glossy (about 1-2 minutes). Remove from heat and allow to cool completely.

Step 05

Make Spice Paste: In a blender, combine cooled rice paste, garlic, ginger, onion, fish sauce (or soy sauce), and sugar. Blend until smooth and uniform. Transfer to a bowl and stir in gochugaru chili flakes, adjusting quantity to desired spice level.

Step 06

Combine Vegetables and Paste: In a large bowl, combine drained cabbage, daikon radish, carrot (if using), and scallions. Add spice paste and, wearing kitchen gloves to protect hands from capsicum, massage thoroughly to coat all vegetables evenly.

Step 07

Pack for Fermentation: Pack the kimchi tightly into clean glass jars or a fermentation crock, pressing down firmly to eliminate air pockets between vegetables. Leave at least 1 inch headspace at the top to accommodate expansion during fermentation.

Step 08

Ferment at Room Temperature: Seal containers and leave at room temperature (65-72°F) out of direct sunlight for 1-2 days. Open jars daily to release built-up gases (burping). Expect bubbling and souring aromas as active fermentation progresses.

Step 09

Refrigerate and Store: Taste after 48 hours; once sour and tangy to your liking, transfer to refrigerator. Kimchi continues fermenting slowly at cold temperatures, developing deeper, more complex flavors over several weeks.
