The definitive Korean fermented cabbage kimchi — crisp, funky, fiery and complex — made from scratch with salted napa cabbage, gochugaru and jeotgal.
Kimchi (김치) is not merely a condiment or side dish — it is the most important food in Korean culinary culture, a 2,000-year-old living fermentation tradition that UNESCO inscribed on its Intangible Cultural Heritage list in 2015. Baechu kimchi, made with napa cabbage (배추), is the most prevalent of Korea's 200+ kimchi varieties and serves as the foundation that defines Korean food globally. The process is deceptively simple — napa cabbage is salted for several hours to draw out moisture and soften the cell structure, rinsed, then coated in a paste of gochugaru (Korean red chili flakes), fermented seafood (jeotgal — saeujeot salted shrimp or myeolchi-aekjeot fish sauce), garlic, ginger, daikon and green onions. The paste penetrates deeply during fermentation, which begins at room temperature and continues slowly in the refrigerator for weeks or months. Freshly made kimchi (geotjeori) is crunchy, bright and mildly spicy. After two weeks it becomes more sour and complex. After months, it develops the deep, funky fermented character prized for kimchi-jjigae and kimchi pancakes. Making kimchi from scratch — particularly the communal winter kimjang tradition — is one of Korea's most important cultural practices.

Quarter the cabbage lengthwise, then cut into 5cm pieces. Toss with coarse salt in a large bowl, working salt between leaves. Let sit 1–2 hours, turning every 30 minutes, until cabbage has wilted and released liquid.
Use non-iodized salt — iodized salt inhibits fermentation bacteria.
Cook sweet rice flour with water in a small saucepan over medium heat, stirring constantly until it becomes a thick, translucent paste, about 3 minutes. Let cool completely. The porridge helps the paste adhere to the cabbage.
Combine gochugaru, cooled rice porridge, saeujeot (or fish sauce), garlic, ginger and sugar. Mix until a smooth, vibrant red paste forms. Add julienned daikon and green onions. Mix well.
Rinse cabbage 2–3 times in cold water to remove excess salt. Squeeze firmly to extract as much water as possible. Taste — it should be pleasantly salty but not overwhelming.
Add cabbage to the paste. Using gloved hands, massage the paste into every layer of cabbage, ensuring thorough and even coating. The paste should penetrate between every leaf.
Wear disposable gloves — gochugaru stains intensely and irritates skin.
Pack kimchi tightly into clean glass jars, pressing down firmly to eliminate air pockets. Leave 3–4cm headspace (it will expand during fermentation). Seal and leave at room temperature 1–2 days until lightly sour. Refrigerate.
Maangchi brand gochugaru gives the most authentic, vibrant red color and flavor — avoid generic chili flakes which taste entirely different.
The kimchi is ready to eat immediately (geotjeori) but at its best complex fermented flavor after 2–4 weeks refrigeration.
For vegan kimchi, replace saeujeot with 3 tbsp soy sauce and 1 tbsp miso paste — this substitution works very well.
Kkakdugi (radish kimchi): substitute cubed daikon for cabbage; ready to eat after just 1 day.
Oi sobagi (stuffed cucumber kimchi): halved cucumbers stuffed with the kimchi paste, fermented just 1–2 hours; served fresh and crunchy.
Fresh kimchi keeps refrigerated up to 3 months (the flavor continues to develop). Beyond 3 months it becomes very sour and is best used cooked — in kimchi-jjigae, kimchi pancakes or fried rice. Never freeze unless specifically making kimchi for cooking.
Kimchi's history in Korea extends at least 2,000 years, documented in the Samguk Sagi chronicles of the Three Kingdoms period (57 BCE–668 CE). Early kimchi was simply salted vegetables without the red chili that defines modern kimchi — gochugaru was introduced to Korea by Portuguese and Japanese traders in the 16th and 17th centuries. The communal winter kimchi-making tradition of kimjang was recognized by UNESCO in 2013 as Intangible Cultural Heritage.
Cold temperatures slow fermentation significantly. If your kitchen is below 18°C, leave kimchi at room temperature 24–48 hours before refrigerating. The beneficial lactobacillus bacteria need warmth to activate initially.
Yes — vegan kimchi is delicious. Replace saeujeot with 3 tablespoons soy sauce and a tablespoon of white miso. The fermented umami note will be somewhat different but the kimchi will still be excellent.
Good kimchi smells sour, tangy and funky — this is correct. Bad kimchi smells rotten, slimy or like acetone. If it smells unpleasant or shows visible mold (as opposed to white kahm yeast on the surface, which is harmless), discard it.
