Ganjang-gejang — Soy-Marinated Raw Crab (간장게장)

Coastal Korea, particularly the West and South coasts where blue crab is harvested; associated with both Joseon court tables and coastal fishing communities as parallel traditions

Ganjang-gejang (간장게장) is called 'rice thief' (밥도둑) for compelling reason: live or freshly killed raw Korean blue crab (꽃게, Portunus trituberculatus) marinated cold in a soy sauce brine for 3–7 days, the result is so intensely savoury and complex that plain rice becomes a vehicle for consuming it. The technique involves making a seasoned soy brine (ganjang + water + garlic + chilli + ginger + sesame) brought to a boil, cooled completely, and poured over cleaned whole crabs; the brine is drained, re-boiled, cooled, and re-poured over the crabs two to three times over successive days. The cold brine 'cooks' the crab through protein denaturation without heat — a form of ceviche logic applied to Korean fermentation principles.

Eaten over plain white rice — the crab's soy-marinated juices mixed into the rice grain by grain is the ritual. One small crab section alongside a bowl of rice constitutes a complete, profoundly satisfying meal. Always served cold.
