Place the ingredients for the sauce in a small mixing bowl and whisk together until fully combined.
Fill a pot with water and bring to a boil. Once the water has come to a boil, drop the noodles in and stir.
Boil the noodles until they soften, about 3 minutes.
Drain into a strainer rinse under cold water until the noodles become cold to the touch.
Place the noodles in a large mixing bowl and toss together with the hot pepper sauce (yangnyum) until all the noodles are well coated.
Divide the noodles into individual bowls and top each with a small pile of cucumber strips, ½ a hard boiled egg and a sprinkle of sesame seeds.
