I’ve been making these spicy buckwheat noodles for years — especially on days when I don’t want to think too hard about dinner. It’s one of those dishes every Korean grows up eating: simple, cold, and incredibly refreshing.

🛒 Ingredients

For the noodles

✔ 2 bundle buckwheat noodles (memil guksu or soba)
✔ Cold water + ice

✔ 2 tbsp gochujang
✔ 2 tbsp soy sauce

✔ 2 tbsp vinegar

👩‍🍳 Instructions

Step 1 – Cook the noodles

Boil the noodles for about 5 minutes. Rinse with cold water, then gently rub them to wash off the extra starch.

2. Make the sauce

Whisk together : 2 tbsp gochujang, 2 tbsp soy sauce, 2 tbsp sugar, 2 tbsp vinegar, 1 tbsp sesame oil, 1 tbsp minced garlic, 1 tbsp gochugaru, and 1 tbsp sesame seeds.

Step 3 – Assemble the bowl

Add the noodles to a bowl, spoon the sauce on top, and finish with cucumber, egg, and any other toppings.

Step 4 – Mix before eating

Right before eating, give everything a good mix so the sauce coats the noodles evenly. This way the flavors stay fresh and the toppings don’t get soggy.
