This refreshing summer noodle dish mixes young summer radish water kimchi broth with green plum syrup and vinegar, freezes it until slushy, and pours it over cooked noodles. Quickly blanching the naengmyeon noodles for under 30 seconds and rubbing them clean in cold water keeps the noodles pleasantly chewy. If the broth tastes too strong, balance it with fresh water, and serve with prepared yellow mustard to taste.

Steps


Here is well-fermented, pleasantly tart young summer radish water kimchi.
I also prepared cucumber and boiled egg for the garnish.


Strain the solid ingredients from the young summer radish water kimchi, then mix green plum syrup and vinegar into the broth to season it sweet and tangy.
For 1 serving, adding about 1 to 2 tbsp green plum syrup (= 1 tbsp sugar) and 1 tbsp vinegar to about 2 1/2 cups water kimchi broth suited my taste.
Also, if the broth tastes too strong, dilute it with fresh water to balance the seasoning.
Now place it in the freezer for about 1 to 2 hours until a thin layer of slushy ice forms.


Drop the naengmyeon noodles into rolling boiling water, stir immediately, and boil for under 30 seconds.
Rub the noodles with your hands while rinsing in cold or ice water to make them bouncy.

Place the naengmyeon noodles in a bowl, pour over the cold noodle broth with floating slushy ice, and finish by generously topping with yeolmu radish greens, julienned cucumber, boiled egg, and ground sesame seeds.
Add plenty of prepared yellow mustard and dissolve it into the broth to enjoy that sharp, nose-tingling kick.
