Instructions
Half-boiled egg
1) Poke a hole in the non-pointed side of the egg with a pin.
2) Bring a pot of water with a little salt to a boil.
3) Place the eggs in boiling water and simmer with medium heat. Rotate the egg in the pot with chopsticks a few times during the process to move the yolk to the center of the egg. Cook the eggs until they become the firmness of your preference.

4) Once the eggs have cooked, immediately place them in an ice water bath and cool down.
5) Peel the shell off the eggs.
Marination
Regular Version
1) Mix the ingredients and heat up to allow the alcohol to evaporate.
2) Cool down the marinade.
3) When cooled, place boiled eggs in a ziploc bag with marinade and let it sit for half a day to a couple of days. Please make sure the bag is air-tight.
Easy Version
Place the boiled egg in a ziploc bag and pour in the mentsuyu so that it is about 1/4 of the way up to the top of the egg. Add the same amount of water to dilute. Mix and taste. Add more mentsuyu and/or water to cover all the eggs until you reach the desired taste.
