Steps
Prepare the ingredients

I prepared about a handful of the yellow inner napa cabbage leaves, and 2 bags of packaged oysters. Once cleaned and drained, they weigh about 150g.
I prepared scallions, but you can also use large green onion, garlic chives, or Cheongyang chili pepper.
How to clean oysters




Dissolve salt in water, then add the oysters and gently swirl them around so any remaining shell fragments come loose and fall away.
Rinse once under running water and drain well.
Slice the ingredients


Cut any large cabbage leaves into bite-sized pieces, and slice the scallions into 2–3 cm lengths.
Boil the soup


Pour in 4 cups of water, and once it comes to a rolling boil, add the cabbage.



Add 1/2 tbsp of minced garlic, 1 tbsp of salted fermented shrimp (saeujeot) brine, and the oysters as well.


Simmer briefly until the cabbage wilts and the oysters cook through, turning the broth a milky white.
If it tastes bland, adjust the seasoning with 1 tbsp of tuna extract sauce (chamchi-aek) or a little salt, then finish by adding the scallions or large green onion.
Finish

Because it is so mild, this is a wonderful soup for elderly family members to enjoy.
My mother has been having a hard time lately with a cold and sore throat, and it warmed my heart to see her eat this so well.
I had one bowl left over and reheated it the next day, and the flavor had deepened and was even more delicious.

Ppunwife's tips
- The secret to making delicious oyster soup is to use minimal seasoning so its inherent flavor comes through.
- It is also tasty to dissolve just a tiny bit of doenjang (Korean soybean paste) into the broth, just enough not to overpower the aroma of the oysters.
- Right before eating, you can finely mince a Cheongyang chili pepper and add it for a spicy kick.
