This is a recipe for Dak Yukgaejang, a typical spicy Korean soup with beef strips and bean sprouts. In this recipe, I use chicken instead of beef -- the idea is to flavor the meat, then let the flavors of the meat ooze into the soup. For a simpler version of this dish, try this recipe for dak yukgaejang, which uses fewer ingredients.
1 cup of cooked fernbrake / bracken fiddleheads (gosari 고사리) -- this usually comes dried
4-5 chicken drumsticks (1½ lb), or chicken breast
4 1/2 cups of water
1 cup (8 oz) bean sprouts (soy bean sprouts -- kongnamul or mung bean sprouts)
1 bunch of green onion
2 tbsp hot pepper powder (gochugaru 고추가루)
1 tsp garlic
1 tbsp light Korean soy sauce (guk ganjang 국간장)
1 tsp sesame oil (chamgirum 참기름)
2 tsp sea salt
1 cube chicken boullion (optional)
dash black pepper
Clean dry fernbrake (gosari) and soak it in a bucket of warm water for an hour or so or overnight if you are not in a hurry.
Discard the dark soaking water and rinse the fernbrake well. Put it in a large pot, put enough water to cover and bring to a boil. Reduce heat and simmer for an additional 15-20 min -- when it gets tender (test by squeezing with your fingers - not mushy though), drain and wash several times until you get clear water. Gosari have a chewy sort of texture so don't overboil.
Cut gosari into about 4" length, so it won’t be too long. Drain and set aside.
Peel the skin of chicken drumsticks and put in a pot with 4 1/2 cups of water. Bring it to a boil and cook for about 20 min or until the meat gets tender.
Remove chicken (keep the stock). Let the chicken cool then using your hands, remove the meat from the bone into small strips into a bowl.
Flavor the chicken: add 2 tbsp of hot pepper powder, garlic, sesame oil, and soy sauce mixing well. Set aside.
Wash the green onions and bean sprouts. Cut into about 4" length and set aside.
Put chicken stock back on the stove, add 2 tsp of salt, dash black pepper and bring it to boil.
Add all of the vegetables except the green onions and bring to a boil. Cook for additional 4-7 minutes, then add the chicken pieces. Cover and cook additional 5 minutes, taste, and adjust salt. You can add chicken boullion for additional taste.
