Okay, so it looks like our main character eats her egg on the side, but the cookbook recipe was for the raw egg in the rice, so I did both. And of course, miso soup. Ready to start the day!
Note the egg isn't quite raw as it should cook a little from the heat of the rice.
Since I don't quite like super goey eggs, I usually pour the whisked egg in the warm pan I reheated the rice in (heat off), and stir quickly before serving for it not turn into scrambled egg.
