Grind toasted sesame seeds until about half has turned into powder
Boil the eggs to your liking and thinly slice the cucumber
Mix together kimchi brine, gochujang, gochugaru, soy sauce, sesame oil, garlic, vinegar, and half of the crushed sesame seeds. Note: If you plan to keep this in the fridge to use later, I recommend leaving out the garlic and sesame oil. These will change the flavor while sitting in the fridge. Just add them when you're about to make your meal. Also: If you don't have any kimchi or brine, that's ok! Increase the soy sauce to 2 tbsp. You will still have a delicious bibim sauce.
Once the sauce is a smooth consistency, add the kimchi.
Boil the somyeon noodles for about 3 1/2 minutes. Be careful with the time because these cook VERY fast. Note: 4 oz is a good amount for one person. That is usually a tad bit bigger than the size of a quarter when wrapping your fingers around the noodles.
Immediately wash under cold water. Rinse it well so you can remove as much starch as possible.
Add the sauce to the noodles and mix. This recipe makes enough sauce for 2-3 servings.
Top with crushed sesame seeds, sliced cucumber, and hard boiled egg.
