I made a version of these yesterday for the first time after seeing the picture on chowhound. Served it with rice and salad for dinner. I really enjoyed the eggs. This picture is mine you can see it came pretty close to the picture in the recipe.
For the marinade I used regular Trader Joe's soy sauce, garlic, hot pepper flakes, and seasoned brewed sushi vinegar instead of mirin. I strained that before adding the eggs. Did this first thing in the morning and they were very nice at dinner time. I have a few left that were not served and have been marinating since yesterday morning.
