Scrape off the mucus between the bones and skin of the catfish, then cut into pieces.
Remove the gills from the catfish head and cut into thick chunks for the soup.
Sprinkle a little salt on the prepared catfish and wash in water to remove the mucus.
To make the broth, boil the radish, half an onion, dried kelp, and dried pollack head in a pot.
When the broth boils, remove the kelp and continue boiling the radish with the broth.
Prepare the shiitake mushrooms, red chili, green chili, and small green onion by slicing them.
Among the prepared vegetables, cut the radish into bite-sized pieces, enough for one soup bowl.
Once the broth is ready, add the radish and vegetables and boil.
When the broth boils, add the prepared catfish and boil.
Season with 2-3 tbsp of soup soy sauce and 0.5-1 tbsp of sun-dried salt.
Add 1 tbsp of minced garlic and 1 tbsp of vinegar, then turn off the heat.
