Steps
Prepare the ingredients

You will need 10 g dried seaweed (miyeok) (store-bought), 1 cucumber, and just a little bit of onion and red chili pepper.


Pour generous amount of water over the seaweed and let soak for at least 10 minutes.
If the water is lukewarm or warm, it expands even faster.
Slice the vegetables

While the seaweed soaks, slice the vegetables.
Cut the cucumber in half lengthwise and slice diagonally into slightly thick pieces, thinly slice the onion, and slice the red chili pepper diagonally into thin slices.
Salt the cucumber


Add 1/3 tsp salt to the cucumber and let it sit for about 20 minutes so it gets lightly seasoned and softens.
It will not taste too salty, so do not rinse it; just squeeze out the excess moisture firmly.
Blanch the seaweed


If the oceanic scent of seaweed does not bother you, you can skip the blanching step.
Add the soaked seaweed to briskly boiling water...


Blanch lightly for under 1 minute.
This method keeps the texture of the seaweed while getting rid of any fishy smell.
Rinse immediately in cold water to remove the heat so it does not cook any further.

Squeeze out the moisture and cut into bite-sized lengths.
Make the sauce


Make the seasoning sauce.
Mix together 2 tbsp gochugaru (Korean chili flakes), 1 tbsp regular soy sauce (jin-ganjang), 1 tbsp gochujang (Korean red chili paste), 1/2 tbsp minced garlic, 2 to 3 tbsp vinegar, 1 tbsp sugar, and 1 tbsp green plum syrup (maesil-cheong).
Toss the ingredients


Add the seaweed, cucumber, onion, and red chili pepper, then toss to combine.
Taste it, add salt if it tastes bland, and finish by adjusting the vinegar or sugar to your preferred sweet-and-sour balance.


Finish by adding 1 tbsp toasted sesame oil and 1 tbsp toasted sesame seeds, then toss together.
Complete the dish


The aroma and chewy texture of seaweed are added to crisp seasoned cucumber, making the flavor even richer.

Try adding seaweed, blanching it only briefly to keep its fresh texture.
Tossed in a sweet and sour dressing, it makes the perfect appetizing side dish to serve with rice.
