If you are using an egg cooker, set it to medium boiled. Otherwise bring a small pot of water to boil and turn the heat off. Carefully add the eggs, cover and let sit for 7 minutes.
Meanwhile, add the ingredients for the marinade in a bowl and stir. Set aside.
Once the eggs are cooked, submerge them in a bowl with ice cold water. Let sit for 5 minutes and peel.
Place the eggs in a Ziploc bag or other sealable container, pour the marinade over and seal. Rotate the eggs every 30 minutes or so, for 2-4 hours. You can let them marinate for up to 2 days for a stronger taste.
Slice in half and serve with ramen or rice.
The longer you marinate the eggs, the stronger the flavor!
