Steps
Prepare the ingredients

This is about half of 1/4 head (1 quarter) of aged sour kimchi.
You also need 1/3 cucumber, Cheongyang chili pepper, boiled egg, prepared yellow mustard, and 1 1/2 cups of kimchi brine.
Slice the ingredients

Finely julienne the cucumber and thinly slice the Cheongyang chili pepper.
Season the kimchi


Place the kimchi in 2 cups of bottled water and swish it around to rinse. Do not discard this water, as it will be used as the cold soup base.
Slice the kimchi crosswise into thin strips so it is easy to pick up.


Add 1/2 tbsp gochugaru, 1 tsp minced garlic, 1/2 tbsp honey, and a little toasted sesame oil and toasted sesame seeds to the kimchi, then mix well.
Rinsing aged sour kimchi or well-fermented kimchi like this and lightly seasoning it again makes it delicious on its own.
Adjust the sugar depending on how sour your kimchi is.
Make the cold kimchi broth


Pour 1 1/2 cups of kimchi brine and 2 cups of bottled water into the 2 cups of kimchi rinse water. (You need 4 cups of bottled water in total, including the 2 cups used to rinse the kimchi.)
Strain out the seasoning solids through a sieve for a clean broth.


Season the broth.
For umami, add 2 tbsp tuna extract sauce, 2 tbsp vinegar...


Add 2 tbsp sugar and 1 tsp prepared yellow mustard, then mix thoroughly.
Once the sugar and mustard are well dissolved, taste and adjust with salt, and tweak the amount of vinegar or sugar to your liking.
Place the prepared cold broth in the freezer for about an hour or two so a light layer of slushy ice forms.
Finish the dish

Boil the thin wheat noodles, place them in a bowl, top with the kimchi, julienned cucumber, chili pepper, and boiled egg, then pour over the cold broth to finish.
