Bring a pot of water to a boil. Ensure the water level is high enough to cover the eggs. Once boiling, reduce to heat to maintain a simmer (small bubbles appearing). Important: Make sure the water is not at a rolling boil!

Insert eggs into pot, all at the same time if possible. Cook for 5 minutes and 45 seconds.

Remove eggs and place in a bowl of ice water for 3-5 minutes. After that, gently remove the egg shells and place eggs into a separate bowl.

Combine all the marinade ingredients together, then pour marinade over the eggs. Using a cling film or kitchen towel, cover the bowl and press the cling film/kitchen towel down such that it is in direct contact with the marinade and eggs. This will ensure the eggs are marinated more evenly.

Marinate the eggs for 4 to 12 hours, rotating the eggs midway through the marinating process. Once done, remove the eggs from the marinade and store them in another container if you wish to consume them at a later date. Otherwise, cut the eggs in half and enjoy them with a bowl of ramen!
