• •Digital kitchen scale
• •Fermentation weight or small sterilized plate
• •Fine sieve and clean cheesecloth
• •Disposable food-safe gloves

Instructions

1. 1

   Choose the fish

   Buy small yellow croaker at their spring peak, firm-bodied, bright-eyed, and clean-smelling. Do not use large dried croaker or fish that has softened at the belly. Jeotgal is preservation, not rescue. If the fish are poor, cook something else from the market that day.

   Ask for hwangseogeo for jeotgal, not gulbi. Gulbi is salted and dried yellow croaker for grilling; this recipe needs small fresh fish for fermentation.
2. 2

   Clean gently

   Rinse the fish quickly in cold running water, rubbing away loose scales and any grit. Leave the fish whole, including heads and bones, but discard any broken fish with torn bellies. Drain in a colander for 30 minutes, then pat very dry with clean towels. Water dilutes the salt and weakens the brine, so drying is not decoration here.

3. 3

   Weigh and salt

   Weigh the drained fish. Use coarse sea salt equal to 30 percent of that weight: for 1.5kg fish, use 450g salt. Toss the fish and salt in a clean stainless bowl until salt reaches the gills, belly folds, and between every layer. 손맛 is real. I still measure it, so it can be handed on.

4. 4

   Pack the jar

   Rinse a 2-liter onggi or glass jar with boiling water and let it dry completely. If using soju, swirl 1 tablespoon inside the dry jar and pour it out. Pack the salted fish tightly, belly to back, pressing out air pockets as you go. Scrape in every grain of salt from the bowl, then scatter the extra 2 tablespoons salt across the top.

5. 5

   Weight and cover

   Set a clean fermentation weight, small plate, or boiled stone on top so the fish stay pressed under their forming brine. Cover with a lid that closes well but does not need to be airtight. Put the jar on a tray, because good jeotgal sometimes pushes up brine in the first week.

6. 6

   Ferment cool

   Keep the jar at cool room temperature, ideally 15 to 20C, for 7 days, then move it to a kimchi refrigerator or ordinary refrigerator at 1 to 5C. Age at least 4 months, and 5 to 6 months is better for kimjang. The brine should turn amber and smell deeply marine and savory, never rotten, fizzy, or moldy.

   If any fish rises above the brine, press it back down with a clean utensil and add a little more salt over the surface. Fish exposed to air spoils before it ferments.
7. 7

   Draw the brine

   In autumn, when the brine is amber and the fish have softened, ladle off the liquid through a fine sieve. For cleaner kimchi, line the sieve with clean cheesecloth. Use 2 to 4 tablespoons brine for a large batch of cabbage kimchi paste, then taste before adding more salted shrimp or fish sauce. This brine has authority. Let it season; don't let it bully the cabbage.

8. 8

   Store safely

   Return the fish to the jar, keep them covered with remaining brine, and refrigerate. Use clean dry utensils every time. Properly salted and kept cold, the jeotgal keeps 6 months or more after opening, but discard it if you see fuzzy mold, gas pressure, sliminess beyond normal fermented softness, or a foul smell.

Chef Tips

• •Use coarse Korean sea salt that has been aged or drained of bitterness if you can. Sharp, wet industrial salt can make the brine harsh, and hwangseogeo-jeot has nowhere to hide that taste.
• •A kimchi refrigerator is the modern vessel that makes this safer for home cooks. 시대가 바뀌면 음식도 바뀌어야 해요. When times change, food must change too. The salt ratio and submerging the fish are not the corners to cut.
• •Do not reduce the salt below 25 percent for this whole-fish ferment. Old houses had cold storage, long practice, and their own microbial habits. A home kitchen needs the stricter measure.
• •Use the brine in kimchi paste before you add other salty ingredients. Hwangseogeo-jeot is deep and clean when used sparingly, but too much makes kimchi taste only of fish.
• •The fermented fish flesh can be minced very finely and added to kimchi paste, 1 to 2 tablespoons per large cabbage, but strain out hard bones if your family does not expect them.

Advance Preparation

• •This is a spring-to-autumn preserve. Salt the fish in late spring and age it 5 to 6 months for kimjang season.
• •The jar can be washed and dried a day ahead. Do not pack fish into a damp jar, because extra water weakens the salt balance.
• •Once aged, strain a small jar of brine and keep it refrigerated for kimchi making. Label it clearly by month and salt ratio so the next batch can be corrected.
