About this dish
Bibim guksu is a chilled Korean noodle dish in which boiled and cold-rinsed somyeon wheat noodles are tossed in a sauce of gochujang, chili flakes, plum syrup, vinegar, soy sauce, and sesame oil.

The heat from the gochujang, the sweetness of plum syrup, and the brightness of vinegar stack into a multi-dimensional flavor in every bite. Rinsing the noodles thoroughly in cold water removes excess starch, giving them a bouncy texture and allowing the sauce to cling evenly. Torn lettuce and julienned cucumber folded in at the end add crunch and release moisture that loosens the thick sauce just enough. A tablespoon of noodle cooking water can thin the sauce if needed. For 100 g of somyeon, a starting ratio of 1 tablespoon gochujang, 1 tablespoon plum syrup, and 1 teaspoon vinegar provides a reliable base to adjust from.
Instructions
Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.
- 1Step
Tear 50 g lettuce into bite-size pieces and julienne 1/2 cucumber thinly.
Briefly soak the vegetables in cold water, then drain well so they stay crisp without watering down the noodles later.
- 2Season
In a mixing bowl, stir 1.5 tablespoons gochujang with 1 tablespoon gochugaru, 1 tablespoon plum syrup, 1 tablespoon vinegar, and 1 tablespoon soy sauce. Add 1 teaspoon sesame oil and mix until glossy.
- 3Control
Bring a generous pot of water to a full boil, then fan in 220 g somyeon so the strands separate.
Cook over medium-high heat for about 3 minutes, lifting when the edges look slightly translucent.
- 4Heat
Move the cooked noodles straight into cold water and rub them between your hands.
Keep rinsing until the water runs clearer and the noodles feel cold, springy, and no longer slippery with excess starch.
- 5Season
Shake off as much water as possible, then toss the noodles with the sauce first so every strand is coated.
If the sauce feels stiff, loosen it with 1 tablespoon noodle cooking water.
- 6Finish
Add the lettuce and cucumber only at the end, folding gently so they do not wilt or break.
Serve while still cold, checking that the sauce coats the noodles without pooling heavily.
