Begin by preparing your noodles, cook them according to packet instructions.
Meanwhile, combine your gochugaru, sugar, tahini, soy sauce, sesame oil, rice wine vinegar, and chilli oil in a small bowl. Taste it and adjust any seasonings based on your preferences.
Place a small saucepan on medium heat and add in your 1 tablespoon vegetable oil, heat for a few minutes.
Once your noodles are cooked, drain and then serve them up in a bowl of your choice. Top with your sliced cucumber, sauce and the garlic and ginger then pour the hot vegetable oil over the top and hear the sizzle. Add in a splash of milk if you want to make your dish extra creamy, and enjoy!
