Instructions
- Cut the napa cabbage in half lengthwise, then slice crosswise into 3–4 cm (about 1½-inch) wide strips. Toss well with the coarse sea salt in a large bowl and let sit for 2–3 hours, turning every 30 minutes.
- Finely mince or grate the garlic and ginger. Cut the scallions into 2 cm (¾-inch) pieces. Whisk the rice flour with 100ml of water until smooth to form a slurry.
- Rinse the salted cabbage thoroughly under cold running water and drain well. Squeeze out the excess moisture by hand or press it in a colander.
- Stir together the gochugaru, garlic, ginger, sugar, fish sauce, and rice flour slurry until you have a uniform seasoning paste. It should be thick but spreadable.
- Combine the drained cabbage, seasoning paste, and scallions in a large bowl and mix thoroughly until everything is evenly coated. Wear gloves — this mixture will stain and irritate skin.
- Pack the seasoned kimchi tightly into sterilized mason jars, pressing down firmly to eliminate any air pockets. The surface should be submerged in its own liquid brine.
- Let the jars ferment at room temperature (65–72°F / 18–22°C) for 3–5 days. Open the jars once daily to release built-up gases and press the kimchi back down beneath the brine.
- Once the kimchi has reached your desired level of sourness, transfer it to the refrigerator. It will keep for 2–3 months and continue to develop in flavor over time.

History & Origin
Kimchi has been a staple of Korean cuisine for centuries, born out of the need to preserve vegetables through long, harsh winters. The now-iconic red variety — made with gochugaru chili flakes — only became widespread after chili peppers were introduced to Korea, likely in the 17th century. In 2013, the collective kimchi-making culture — the communal practice of preparing and sharing kimchi known as ‘Kimjang’ — was recognized by UNESCO as an Intangible Cultural Heritage of Humanity.
Variations
- Vegan version: Swap the fish sauce 1:1 for light soy sauce — the umami character holds up well and the overall flavor is just a touch milder.
- Kkakdugi (radish kimchi): Use cubed daikon radish instead of napa cabbage — shorten the salting time to 1–2 hours, and expect a crunchier texture with an earthy, mildly spicy flavor all its own.
- Milder heat: Cut the gochugaru in half and add a tablespoon of gochujang (fermented chili paste) — you get more depth and complexity with less raw heat on the finish.
- Oi sobagi (stuffed cucumber kimchi): Score small Persian or Kirby cucumbers crosswise, stuff them with the seasoning paste, and ferment for just 1–2 days — a quick, fresh, and crisp side dish that’s perfect in summer.
Common Mistakes – and How to Avoid Them
- Under-salting or not salting long enough: The cabbage needs to sit in salt for at least 1–2 hours until it is noticeably soft and pliable — if you rush this step, the texture after fermentation will be tough instead of pleasantly crisp.
- Not rinsing off the salt thoroughly: A quick rinse will leave you with an overly salty finished product — rinse under cold water at least three times and let the cabbage drain well before proceeding.
- Air pockets in the jar: Loosely packing the kimchi creates gaps where unwanted microbes can thrive instead of beneficial lactic acid bacteria — always press the kimchi down firmly and make sure it stays submerged in brine.
- Fermenting at the wrong temperature: Below 60°F (15°C) fermentation barely gets going; above 77°F (25°C) the kimchi will turn overly sour and mushy very quickly — aim for 65–72°F (18–22°C) during the initial fermentation period.
- Substituting regular chili powder for gochugaru: Standard chili powder is significantly hotter and lacks the fruity, mellow aroma of gochugaru — the result will taste sharp and bitter rather than complex and savory. Gochugaru is widely available at Asian grocery stores and online.
Storage & Shelf Life
Fully fermented kimchi keeps in the refrigerator at 35–41°F (2–5°C) for at least 4–6 weeks, and often much longer — the flavor deepens and becomes more sour over time. To freeze, portion the kimchi into zip-top freezer bags, press out the air, and freeze for up to 3 months; it will lose some of its crunch after thawing but works beautifully in cooked dishes. Kimchi is not meant to be reheated on its own — serve it cold or at room temperature; for cooked recipes like kimchi jjigae (kimchi stew), add it straight from the jar into the pan.
What to Serve With It
Kimchi is the classic companion to steamed white rice and is an inseparable part of a Korean table, where it is served as a banchan (small side dish) alongside nearly every meal. For a more Western spin, kimchi is a game-changer stirred into scrambled eggs, piled on avocado toast, or served alongside grilled meat, adding a tangy, spicy punch. To drink, cold Korean lager, a crisp dry Riesling, or a simple green tea all pair beautifully. At cookouts or dinner parties, kimchi makes a bold and unexpected alternative to pickles — and it almost always gets the conversation going.
Frequently Asked Questions
- How do I know if my kimchi is fermenting properly?
- Properly fermenting kimchi will bubble gently, smell pleasantly sour (not rotten), and taste tangy with a spicy kick. A white film on the surface is usually kahm yeast — it’s harmless, but skim it off and consume the kimchi sooner rather than later.
- Can I make kimchi vegan without fish sauce?
- Absolutely. Just swap the fish sauce for an equal amount of soy sauce or a vegan fish sauce alternative. Adding a small amount of dried seaweed (such as wakame) to the paste will boost the umami depth even further.
- Why isn’t my kimchi getting sour enough?
- Temperatures that are too low or chlorinated water can slow or stall fermentation. Make sure your kitchen is between 65–72°F (18–22°C) and that you’re using filtered water. If fermentation is still sluggish, stir in a tablespoon of already-fermented kimchi as a starter culture.
