  • 1 oz dried anchovies for soup (guk myeolchi 국멸치) 30 g
  • 1 piece dried kombu (kelp) or dashima 다시마 approx 3.5 in x 1.5 in
  • 8 cups water
  • 1.25 lb Korean radish (mu 무), julienned 600 g or 5 1/2 cups
  • 3 Tbs Deonjang I used Jayone here
  • 1 Tbs red miso
  • 1 Tbs Jaerae Doenjang Traditional slow fermented - optional but best for flavor
  • 1 tsp Guk Ganjang Soysauce for Soup - optional to taste
  • 1 Tbs garlic chopped (if using frozen, add more)
  • 1 tsp garlic powder
  • 2 green onions
  • 1/2 tsp red chili powder gochukaru 고추가루


  • Add 8 cups of water to pot. Add dried anchovies and dried kombu kelp. Heat on medium low heat for 20 min. Do not boil.
  • While anchovy stock is developing, cut radish into large chunks and then into slices, then julienne into thin 0.5 cm (0.2 inch) sticks. A little thicker or about the same as size of shoestring fries.
  • When anchovy stock is ready (yellowish color), remove anchovies and kelp from pot.
  • Add all 3 soybean pastes from above if they are available. If not, just use 3 or 4 Tbs Korean soybean paste (whatever you have) and 1 Tbs red miso to pot. Mix well into the soup by smooshing the paste against the side of the pot with a spoon and swishing it around.
  • Add radish sticks to soup and bring to boil on medium high heat.
  • Simmer for 25 minutes or more until radishes are soft and tender.
  • Add cut green onions, chopped garlic and garlic powder and simmer for 5-10 more minutes.
  • Taste the soup. Add 1 tsp guk ganjang if you think it needs a little more salt. Remember guk ganjang not only adds salt but also tons of umami flavor so add this if you think it lacks that something.
  • Finish with some red chili powder (gochukaru). Add more if you want it more spicy.


Serve hot with rice, kimchi and other side dishes and it will make a wonderfully comforting meal.
