When it is not too thin and feels slightly thick, that is the perfect consistency.
Keep it cold in the refrigerator or freezer, then boil thin wheat noodles and enjoy it refreshingly cold.
Boil the noodles


Add thin wheat noodles (somyeon) or medium-thick wheat noodles (jungmyeon) to vigorously boiling water, boil until chewy, and drain the water completely...
Finish the dish

Place julienned cucumber garnish over the boiled thin wheat noodles and pour in the soybean broth.
I floated small ice cubes so it stays cold the entire time you eat.
If you chill the soybean broth in advance, the ice will not melt quickly and it stays cold the entire time you eat.
