Baechu-kimchi: Primary Dry Salting (jeol-igi 1 stage)

Traditional Korean preservation technique, refined over centuries in coastal regions where sea salt was abundant

The first salt application extracts free moisture from the cabbage through osmosis while beginning to break down the rigid cell walls. Coarse sea salt (cheon-il-yeom) — solar-evaporated, harvested from the tidal flats of Sinan County in South Jeolla Province — is the only correct choice. Table salt or fine salt draws water too aggressively and leaves a harsh, one-dimensional salinity. Apply coarse salt between every leaf layer, concentrating on the thick white stem portions that hold the most water. The ratio is roughly 1 cup of coarse sea salt per medium head of cabbage. After initial salting, turn the cabbage quarters every 30 minutes for 2 hours, ensuring even exposure.

• Similar osmotic salting principles are used in Japanese nukazuke and Sichuan paocai, though salt concentration and timing differ

Proper salting creates the texture — the satisfying crunch in finished kimchi that no shortcut can replicate. Under-salted kimchi ferments unevenly and becomes mushy within days
