Cook the noodles
Bring a pot of water to a boil and cook the Shin Ramyun noodles for 3 minutes.
Add a bowl of cold water to the pot to bring the temperature down slightly, then continue cooking for another 1 minute.
Drain the noodles and rinse thoroughly under cold running water until completely chilled.
Transfer the noodles to an ice bath while you prepare the sauce.
Make the sauce
Add the chopped kimchi, kimchi juice, rice vinegar, soy sauce, oyster sauce, gochujang, gochugaru, sugar, garlic, sesame oil, Shin Ramyun seasoning and MSG to a bowl.
Mix everything together until well combined, then taste and adjust to liking.
Mix the noodles
Drain the noodles really well, then add them to the bowl with the sauce.
Give everything a really good mix until the noodles are completely coated in that spicy, kimchi-packed sauce.
Serve
Transfer the noodles to a bowl and top with julienned cucumber, half a soft-boiled egg and sesame seeds.
Finish with a little extra sesame oil and dig in immediately!
