Spicy Fermented Korean Cabbage (Printable Version)

Traditional Korean fermented napa cabbage with chili, garlic, and ginger for a spicy, tangy, probiotic-packed side dish.

# What You'll Need:

→ Produce

01 - 1 large napa cabbage, about 2.5 lbs
02 - 1 medium daikon radish, about 7 oz, julienned
03 - 4 scallions, sliced
04 - 1 medium carrot, julienned (optional)

→ Salt & Water

05 - 1/3 cup coarse sea salt
06 - 6 cups cold water

→ Spice Paste

07 - 6 cloves garlic, minced
08 - 1 thumb-sized piece fresh ginger, peeled and minced
09 - 1 small onion, roughly chopped
10 - 3 tablespoons fish sauce or soy sauce for vegan version
11 - 1 tablespoon sugar
12 - 3 to 5 tablespoons Korean red chili flakes, to taste
13 - 2 tablespoons rice flour
14 - 2/3 cup water

# How-To Steps:

01 - Cut the napa cabbage lengthwise into quarters, then chop into 2-inch pieces.
02 - Dissolve sea salt in 6 cups cold water in a large non-reactive bowl. Add cabbage pieces, tossing to coat. Place a plate and a weight on top to keep submerged. Let sit for 2 hours, tossing every 30 minutes.
03 - Rinse the salted cabbage thoroughly under cold water 2 to 3 times to remove excess salt. Drain well.
04 - Whisk rice flour with 2/3 cup water in a small saucepan over medium heat until thickened, about 1 to 2 minutes. Let cool to room temperature.
05 - In a blender, combine cooled rice paste, garlic, ginger, onion, fish sauce or soy sauce, and sugar. Blend until smooth. Stir in Korean red chili flakes to desired spice level.
06 - In a large bowl, combine drained cabbage, daikon radish, carrot if using, and scallions. Add spice paste and using kitchen gloves, massage thoroughly to coat all vegetables.
07 - Pack the kimchi tightly into clean glass jars or a fermentation crock, pressing down to eliminate air pockets. Leave at least 1 inch headspace at the top.
08 - Seal and leave at room temperature out of direct sunlight for 1 to 2 days, burping the jars daily to release gas.
09 - Taste after 48 hours; once sour and tangy to your liking, store in the refrigerator. Kimchi will continue to ferment slowly and develop deeper flavors over several weeks.

# Expert Advice:

01 -
  • You'll taste the exact spice level you crave instead of guessing at store shelves.
  • Your gut gets a live probiotic boost that tastes genuinely delicious, not like a chore.
  • One batch keeps giving for weeks, getting tangier and more complex as days pass.
02 -
  • Under-rinsing the cabbage after the salt brine is the number one reason homemade kimchi tastes too salty; take the extra minute to rinse properly.
  • Those daily burps (opening the jar) matter because trapped gas pressure can pop your lid or create an unsafe fermentation environment.
03 -
  • Always use non-reactive bowls and jars (glass or ceramic work best) because metal reacts with the salt and fermentation acids.
  • If white mold forms on the surface, it's usually harmless wild yeast, but if it looks slimy or smells off, toss the batch and start fresh.
