Bring a medium pot (with one egg in it) to a boil. Hard boil your egg as long as you desire. Six minutes for a jammy egg, or a full eight for hard boiled. At the same time cook your noodles in the hot water for a few minutes, according to package directions.
In the meantime, whisk together the soy sauce, sesame oil, brown sugar, egg, mayo and sambal in a serving bowl. Add ½ cup of the starchy water to the mix (once the noodles are cooked) and whisk it one more time. There’s your soupy sauce!
Ladle the noodles into the sauce and garnish with the split egg, scallions, sesame seeds and a drizzle of hot oil! (Totally optional, but do it.)
Serves one.
