Jogae-jeot (조개젓, Salted Clams)

Ingredients

Equipment Needed

• •Digital kitchen scale
• •Nonreactive bowl large enough for purging clams
• •Clam knife or sturdy oyster knife
• •Fine-mesh sieve
• •Sterilized 500ml glass jar with tight lid
• •Small clean spoon for daily stirring

Instructions

1. 1

   Choose live clams

   Buy the clams the day you salt them. They should be closed or close when tapped, heavy for their size, and smell like clean seawater, not ammonia. Throw away cracked shells and any clam that stays open. Salt can preserve good shellfish; it cannot rescue bad shellfish.

2. 2

   Purge the sand

   Dissolve 60g salt in 2 liters cold water in a nonreactive bowl. Add the clams, cover, and refrigerate 2 hours. This 3 percent brine is close enough to seawater that the clams spit sand; fresh water shocks them and leaves you with grit. Lift the clams out of the bowl instead of pouring them out, so the sand stays behind.

   Keep the bowl cold and dark while the clams purge. A tray or lid over the bowl calms them, and calm clams give up more sand.
3. 3

   Shuck and weigh

   Set a clean bowl over ice. Open the clams with a clam knife, cutting the meat free and saving the liquor. Strain the liquor through a fine sieve. From 1.5 kg live clams, expect about 280 to 330g meat. Weigh the meat after draining. Notebook 24 says 15g salt for every 100g clam meat. That is the line between preserve and wishful thinking.

   If the shells fight you, put the purged clams in the freezer for 20 minutes to loosen them, then shuck while still cold. A brief blanch opens them faster, but it changes the texture and shortens the keeping time.
4. 4

   Salt the clams

   Mix the clam meat with 45g salt, adjusting if your shucked weight is different: use 15 percent salt by weight. Pack the salted clams into a sterilized 500ml glass jar with 2 tablespoons strained clam liquor. Press them down so the liquid rises around them. If the clams are not barely moistened, dissolve 1 teaspoon salt in 2 tablespoons boiled and cooled water, then add only enough to cover the top.

5. 5

   Ferment cold

   Cover the jar and refrigerate at 0 to 4 C for 3 days. Once a day, open it with clean hands, stir with a clean spoon, and press the clams back under the brine. The cure is ready when the brine is lightly cloudy and the clams taste briny, soft, and clean, without a raw metallic edge. If you see mold, swelling, strong sourness, slime, or any rotten smell, throw it away without bargaining.

6. 6

   Dress a serving

   Lift out 150g cured clams for the table and leave the rest plain in the jar. Taste one. If it is too salty to eat with rice, swish only this portion in 3 tablespoons cold water for 5 seconds, then drain well. Mix with the gochugaru, garlic, scallion, chili if using, maesil-cheong if using, sesame oil, sesame seeds, and 1 teaspoon jar brine if the mixture needs loosening. Rest 10 minutes before serving so the chili blooms and the scallion settles.

7. 7

   Serve and keep

   Serve in spoonfuls, 1 to 2 tablespoons per person, beside plain rice and gim (roasted seaweed). Do not return leftovers from the table to the jar. The plain salted base keeps up to 2 weeks refrigerated if it stays under brine and you use a clean spoon. Once dressed with scallion and sesame oil, eat it within 3 days.

Chef Tips

• •This is raw shellfish. Salt and cold slow trouble; they do not make unsafe shellfish safe. Serve it only if you would trust those clams raw, and avoid it for pregnant people, young children, older adults, or anyone immunocompromised.
• •Do not reduce the curing salt below 12 percent of the shucked clam weight. If you want it less salty, rinse the small portion you are dressing. The storage jar needs its salt.
• •Dress only what the table will eat in a few days. Garlic, scallion, and sesame oil make the banchan generous, but they also shorten its keeping life.
• •A glass jar is a good modern vessel here. Onggi has its place, but for a small raw shellfish preserve, a sterilized jar in a cold refrigerator lets you see and control what is happening.
• •Canned clams will not become jogae-jeot. If that is what your market has today, make a quick clam muchim with gochugaru, scallion, garlic, and sesame oil, and save this recipe for live spring clams.

Advance Preparation

• •Day 1 is for buying, purging, shucking, weighing, and salting. Do not buy live clams and leave them waiting for another day.
• •The salted base is ready after 3 days in the refrigerator and can continue to deepen for 5 days, but for a home batch I stop there and keep it cold.
• •The plain salted base keeps up to 2 weeks refrigerated at 0 to 4 C. The dressed portion is best in the first 24 hours and should be finished within 3 days.
