8 large eggs, at room temperature (farm fresh if possible)
¾ cup soy sauce
Fill a medium-sized saucepan three-quarters full with water and bring to a boil. Add the eggs gently into the boiling water. Boil for 6 to 8 minutes depending upon desired firmness of yolk. Set a large bowl in the kitchen sink and fill with cold water. Scoop the eggs from the boiling water and immediately plunge into the water.
Run more cold water if the water temperature feels warm. When the eggs are cool, gently crack by rapping and rolling . Return the eggs back to the cold water for a few more minutes, then peel.
Lay the peeled eggs on a dry dish towel. Pat dry, and then place the eggs in a freezer-style gallon resealable plastic bag. Pour in the soy sauce, tip the bag to distribute, press out all the air, and roll up any unused portion of bag to create a tight cylinder.
Refrigerate overnight. Serve before dinner with drinks, as a side dish for a barbecue or picnic or in Ramen.
Best the first day.
