They’re called shoyu tamago in Japanese; the simplest English translation of the Chinese name is braised soy sauce eggs. They are served as a snack, as a topping for congee or as one of the many dishes in a bento box.
The name might suggest that there’s nothing to making this delicacy but soaking boiled eggs in soy sauce but there’s a little bit more to it than that.
First of all, “boiled” doesn’t necessarily mean hard-boiled. The eggs can be a little less cooked so that the yolks are still runny. The egg white, however, must be sufficiently cooked so that it is firm enough that when the egg is shelled, it doesn’t break and expose the soft yolk.
Second, the soy sauce in which the eggs are soaked isn’t soy sauce alone. A few other things are added. Rice wine and rice vinegar are not uncommon but other seasonings such as black pepper or chilies can be added too.
Third, the eggs don’t benefit from a really long soaking time. Leave them in the soy sauce mixture for too long and the eggs will turn out too salty. Fifteen minutes or so are enough to allow the eggs to acquire a good color and to absorb the flavors in the sauce.
If, however, you are not in a hurry to serve the eggs, you can soak them in the fridge overnight BUT you will have to dilute the soy sauce mixture with water. I did not want to do that because I wanted the soy sauce mixture to be usable for seasoning other dishes in the future. [Read more...]
