About this dish
Yangpa jangajji is a soy-pickled onion made by immersing large-cut onion chunks in a boiled brine of soy sauce, vinegar, and sugar.

The hot brine tempers the raw onion's sharp, pungent bite on contact, and as the pickle matures in the refrigerator the sweet-salty seasoning penetrates evenly through each piece. Cutting the onion along its fiber rather than against it keeps the texture firm and crisp after pickling, whereas thin cross-cut slices tend to soften quickly in the acidic brine. Sliced cheongyang chili peppers added to the jar gradually release their heat into the liquid, lending a gentle, lingering spiciness that offsets the sweetness and keeps the flavors from becoming one-dimensional. The pickle is ready after one day of refrigeration but improves noticeably at three days or more as the seasoning continues to deepen. It is a staple accompaniment to grilled meats like samgyeopsal, where its acidity and crunch cut through richness and refresh the palate between bites. It also works well over bibimbap or cold noodles. The brine can be brought back to a boil and reused for a second batch of onions, making this an economical pantry item.
Ingredients
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Prep
Peel 500 g onion and cut it into large pieces along the natural fibers so the texture stays crisp.
If the onion tastes very sharp, soak it in cold water for 10 minutes, then drain it well.
- 2Prep
Slice 2 hot green chilies on a diagonal, keeping loose seeds from scattering too much.
Put the onion and chilies into a sterilized jar, packing them firmly enough to fit but not crushing the onion pieces.
- 3Control
Combine 180 ml soy sauce, 180 ml vinegar, 180 ml water, and 4 tablespoons sugar in a saucepan.
Set it over medium heat and stir until the sugar dissolves before the liquid reaches a full boil.
- 4Control
When the brine begins bubbling across the surface, boil it for about 1 minute only.
Turn off the heat before it reduces heavily, so the vinegar keeps enough acidity and the soy flavor does not become too salty.
- 5Control
Pour the hot brine directly into the jar until the onions are covered.
Press the vegetables down with a clean spoon to release trapped air, then let the jar cool completely at room temperature before refrigerating.
- 6Finish
Refrigerate for at least one day; the seasoning becomes more even after 3 days.
Use clean, dry tongs to remove only the portion needed and serve it cold.
