Put eggs into the pot

Pour ~5 cups of water into the pot to fully cover the eggs

Turn on the stove and begin boiling the water. Occasionally, stir to rotate the eggs

Pour 150 mL (~0.6 cups) of water into a separate pot to begin making the sauce

Add 150 mL of soy sauce into the sauce pot

Add 5 mL of mirin into the sauce pot

Add 50 mL of cooking alcohol into the sauce pot

Add 3/4 tsp of dashi into the sauce pot

Begin boiling the sauce

After the water begins to boil, boil the eggs for 7 minutes

After the sauce begins to boil, turn off the heat and allow to cool

Prepare some ice water and place the eggs inside to easily peel the boiled eggs

Place the eggs and and sauce into a large zip-lock or similar type of bag

Place in the fridge for at least 30 minutes. If you wait overnight, they will taste even better as the flavor infuses into the egg
