Ingredients

For the Crabs

• 4 live blue swimming crabs (about 400-500 g each)
• 1/2 cup coarse sea salt, for purging
• Cold water, for soaking

For the Soy Marinade

• 2 cups Korean soy sauce (jin ganjang)
• 1/2 cup water
• 1/3 cup rice syrup (jocheong) or packed brown sugar
• 1/4 cup Korean rice wine (cheongju) or sake
• 1 small Korean or Asian pear, peeled, cored, and sliced
• 1 small yellow onion, sliced
• 10 garlic cloves, smashed
• 1 (1-inch) knob fresh ginger, sliced

For Serving

• 2 tablespoons toasted sesame oil
• 2 cups steamed short-grain white rice
• 4 steamed eggs (gyeran jang), optional
• 1 bunch fresh perilla leaves or lettuce cups

Directions

1. 1. Purge the live crabs in a large bowl of cold salted water (1/2 cup salt per 4 liters water) for 2-4 hours, changing the water once, so they empty their stomachs.
2. 2. Scrub each crab under cold running water with a stiff brush, then pull off the top shell and discard the gills, mouth, sand sac, and apron. Rinse well and pat dry with paper towels.
3. 3. Using a heavy knife or kitchen shears, cut each crab into 4-6 pieces, leaving the legs attached. Crack the claws and leg joints slightly so the marinade can penetrate the meat.
4. 4. In a large non-reactive pot, combine the soy sauce, water, rice syrup, rice wine, pear, onion, garlic, and ginger. Bring to a gentle boil over medium heat, then reduce and simmer 8-10 minutes to soften the aromatics and dissolve the syrup. Remove from heat and cool completely to room temperature.
5. 5. Layer the crab pieces in a large glass or ceramic container (avoid metal), tucking some of the cooked aromatics between each layer.
6. 6. Pour the cooled marinade over the crab until fully submerged. Press a small plate directly on the crab to keep it immersed. Cover tightly and refrigerate for 24-48 hours, gently turning the container once at the halfway point.
7. 7. To serve, lift the crab pieces out of the marinade and arrange them on a chilled plate. Drizzle generously with toasted sesame oil.
8. 8. Serve very cold with steamed rice, steamed eggs, and lettuce or perilla leaves for wrapping. Spoon a little of the strained marinade over the rice if desired.

Cook’s Notes

• Source only the freshest live crabs from a reputable seafood market; freshness is non-negotiable for this raw preparation.
• Use Korean jin ganjang (regular brewed soy sauce), not the darker, thicker soup-style soy sauce reserved for stews.
• Marinate no longer than 3 days or the delicate crab texture can turn mushy; 36-48 hours is ideal.
• Reserve a small jar of the strained leftover marinade to use as a dipping sauce for the steamed eggs and rice.
• Pregnant women, the elderly, and immunocompromised individuals should avoid this raw seafood dish.
