Wash the boiled radish greens thoroughly and cut them into 5cm pieces.
Mix doenjang (soybean paste), perilla seed powder, and minced garlic with water to make a seasoning broth.
In a pot, add the radish greens, seasoning broth, and anchovy-kelp stock.
Boil over medium heat until the radish greens become tender, then season with soup soy sauce and salt to taste.
Cover with a lid and simmer until most of the liquid is reduced, then drizzle in perilla oil to finish.
