These eggs are really different from your standard hard boiled eggs and my kids love to have the in their bentos. The trick is to only medium boil the eggs initially and then crack or peel them and finish them off in the soy sauce broth. I use the smallest eggs I can find to do these, so that my kids can have two eggs and I don't have to feel guilty. The eggs aren't supposed to be overwhelmingly seasoned, but if that's what you're looking for, leave them in the broth for a longer period after boiling. I routinely double the recipe by increasing the number of eggs, but leave the amount of the broth ingredients the same.
