Boil water in a kettle or in a large pot. Add your egg and make sure you take a look at the time ◡̈ If you want a soft boiled egg, it will take 7 minutes. Hard boiled will be 8-9 minutes.

Mix sauce (from Step 1) with the strained noodles. I like to use my hand with a glove to mix throughly.
Top mixed noodles with sliced cucumbers, boiled eggs, and sesame seeds. This is optional but highly recommended; add some roasted seaweed on top. Please enjoy fresh so the noodles are not soggy.
