Spicy Fermented Korean Kimchi (Printable)

A zesty Korean fermented side dish with napa cabbage, radishes, and chili. Rich in probiotics and umami.

# What You Need:

→ Produce

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

→ Salt and 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

# Directions:

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 and toss 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, approximately 1 to 2 minutes. Let cool completely.
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 -
  • It tastes alive—literally alive—with probiotics that make your gut happy and your taste buds sing.
  • Once you make it once, you'll realize store-bought kimchi was just practice; homemade is where the real magic lives.
  • Watching vegetables transform into something tangy and complex over a few days feels like kitchen alchemy.
02 -
  • Don't skip the rinsing step or your kimchi will be unpleasantly salty—I learned this the hard way and had to start over, which taught me patience.
  • The fermentation timeline is a suggestion, not a law; taste it at 24 hours and again at 48 hours because variables like room temperature and jar size change everything.
  • Kitchen gloves are non-negotiable unless you enjoy the sensation of chili-oil hands for three days afterward, which I do not recommend.
03 -
  • Use glass jars with plastic lids rather than metal; metal can react with the acidic fermented vegetables and create off-flavors over time.
  • If you're vegan, vegan fish sauce exists and is genuinely delicious, or stick with soy sauce, which creates a slightly different but equally delicious final product.
