Traditional Kimchi

Why This Traditional Kimchi Works

Salt and time do most of the work here. While the cabbage sits in the salty water, a lot of its water comes out. The leaves bend and soften but still stay in one piece. Because the cabbage is no longer full of extra water, it can soak in the ginger, garlic, fish sauce, and red pepper instead of watering them down. After rinsing, the cabbage is flexible and a little salty all the way through, so the seasoning can cling to every leaf.

Once everything is packed into the jar, pressing it down squeezes out air pockets and pulls more liquid from the cabbage and vegetables. That liquid rises and covers the cabbage, so it stays under the brine instead of drying out. Over the next few days, tiny bubbles start to form as it ferments. The cabbage, daikon, and carrot slowly become more sour and tangy, while staying crunchy instead of mushy, because the salt has already tightened them up.

Mistakes To Avoid

Oversalting the cabbage brine or leaving the cabbage in it for too long can pull out too much water. The leaves then turn tough and leathery instead of staying flexible, and the finished kimchi stays overly salty and hard to chew, even after fermenting.

Rinsing the salted cabbage too lightly leaves a lot of surface salt. During fermentation this extra salt slows everything down, so the kimchi can stay harshly salty and doesn’t sour evenly, with some parts tasting flat and others sharp.

Packing the cabbage loosely in the jar, without pressing out air pockets, lets big bubbles of air sit between the leaves. Those spots can grow surface mold or turn brown and mushy, while the parts that stayed under the liquid ferment normally, giving a jar with mixed textures and some spoiled sections.

Letting the jar sit in a very warm place or for too many days at room temperature pushes the fermentation too fast. The cabbage breaks down too much, turning stringy and limp, and the liquid can turn fizzy and sharp in a way that feels harsh rather than pleasantly tangy.
