Napa Cabbage Kimchi (통배추김치)

Kimchi is the single most important food in Korean cooking. It appears at every meal, breakfast through dinner, and the act of making it, kimjang, is a communal ritual that UNESCO has recognized as an Intangible Cultural Heritage of Humanity. Every Korean family has their own recipe, adjusted over generations, and the variations are endless. This is the traditional tongbaechu version: whole cabbage leaves, salted, rinsed, and packed with a paste of gochugaru, fish sauce, garlic, ginger, and rice flour porridge.

The process takes time but very little skill. You salt the quartered cabbage for six to eight hours until the thick white parts bend without snapping. You rinse it three times and drain it. You make a rice flour paste that will feed the lactobacillus bacteria during fermentation. You build the kimchi paste, a vivid red mixture of gochugaru, fish sauce, garlic, ginger, and blended onion. You fold in matchstick radish, carrot, scallions, and chives. Then you work through the cabbage, spreading the paste between every leaf, and fold each quarter into a tight bundle.

The bundles go into an airtight container, pressed down to eliminate air pockets, and sit at room temperature for one to two days. During this time, the lactobacillus bacteria produce lactic acid, carbon dioxide, and the complex sour-spicy-umami flavor that makes kimchi kimchi. Then it goes into the refrigerator, where fermentation continues slowly for weeks and months. Fresh kimchi is mild and bright. Week-old kimchi is tangy. Month-old kimchi is deeply sour and complex, the kind that makes the best kimchi jjigae and kimchi fried rice.
