About this dish
Jangeo-tang is a nourishing Korean eel soup in which freshwater eel is boiled, deboned, and simmered in a seasoning base of doenjang and gochugaru.

Dried radish greens (sirae-gi) are added to the pot for an earthy, faintly bitter depth that grounds the overall richness. Garlic and green onion work against any fishiness, leaving behind the clean, fatty character of the eel itself. What distinguishes this broth from a straightforward spicy soup is the interaction between the fermented weight of doenjang, the direct heat of gochugaru, and the rendered fat of the eel: the three together produce a complexity that neither doenjang nor chili achieves alone. The eel meat holds its grain even with extended cooking, remaining tender without falling apart. Rich in protein and unsaturated fats, this soup has long been categorized as a stamina-restoring food in Korean culinary tradition, consumed during the three hottest periods of summer or whenever the body needs rebuilding. Sliced green chili or perilla seed powder can be stirred in to shift the broth's profile.

Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Control
Clean 800 g freshwater eel and cut it into large pieces.
Place it in 1600 ml water, bring to a steady boil over medium heat, and cook for 20 minutes to draw out excess fat and strong aroma.
- 2Finish
Lift out the cooked eel and let it cool until it can be handled.
Separate only the flesh, checking carefully for small bones and skin so the finished soup has a clean texture.
- 3Heat
Strain the eel cooking liquid through a fine sieve and return it to the pot.
If a thick layer of fat floats on top, skim some off so the broth stays clear rather than heavy.
- 4Season
Whisk 1 tablespoon doenjang into the broth first until no lumps remain.
Add 2 tablespoons gochugaru and 1 tablespoon minced garlic, then keep the pot at a medium boil to bloom the seasoning.
- 5Control
Add 150 g dried radish greens and simmer for 12 minutes.
Keep the heat moderate, not fierce, until the stems soften and the broth turns red and earthy without reducing too much.
- 6Finish
Add the reserved eel flesh and 1 sliced green onion.
Simmer gently over medium-low heat for 8 more minutes, stopping when the eel is tender, the broth tastes balanced, and the pieces still hold their shape.
