First, we'll start by boiling the eggs. Boil the water and when it comes to a boil, gently lower the eggs into the water. Also, prepare an ice bath for the eggs (in a bowl place a lot of ice and add some water (enough to cover the eggs when they come out).
Boil for 6.5 minutes or to your desired yolk consistency. I like them a little runny but creamy (as pictured) which you should get at 6.5 minutes. Feel free to boil them longer, if you'd like a more solid yolk.
When the eggs are done, remove them from the hot water and immediately add them to your ice bath to stop the cooking process.
Next, to a container (I would recommend something taller and a little skinnier so all the eggs can be submerged), add the soy sauce, vinegar, garlic, chilies, green onion, and sugar and stir until the sugar is dissolved.
Peel and add your eggs to the soy sauce mixture.
Allow to marinate - 1-hour minimum, 4-8 hours preferred.
Once the marinating process is complete, add to the desired dish or eat solo! Be sure to finish the eggs in 2-3 days.
