Crack 3 egg into a mixing bowl and add ½ tbsp sugar, 1 tbsp sake and 1 pinch salt. Whisk them together until well combined.
Take a non-stick pan and heat it on medium. Add a small drizzle of cooking oil and pour in the egg. Allow it to firm up a little before mixing to make it scrambled.
Transfer the scrambled egg to a bowl and set aside for later. Wipe out the pan to remove any egg residue.
Return the pan to the heat and add 150 g ground chicken. (Add a little more oil if necessary.) Cook until lightly browned.
Add 1 tbsp Japanese soy sauce (koikuchi shoyu), 1 tbsp oyster sauce, 1 tbsp sake, 1 tbsp mirin and 1 tbsp sugar to the mince and cook on a high heat until the liquid is completely reduced.
Once all the liquid is gone, remove the pan from the heat.
Bring a small pot of water to a rolling boil and add 1 pinch salt. Add 60 g Oriental spinach and blanch for 1 minute. Once done,
Drain the water and place the blanched spinach in a small bowl. Add 1 tsp Japanese soy sauce (koikuchi shoyu), 1 pinch sugar, 1 tsp toasted sesame oil and ½ tsp toasted white sesame seeds, and mix thoroughly.
Dish up 2 portions cooked Japanese short-grain rice into separate serving bowls.
Arrange the egg, soboro chicken and greens on top.
Garnish with 1 tsp red pickled ginger (benishoga) (optional) on each portion and enjoy!
Notes
If you can’t find sake then you can substitute with dry sherry or white wine. The alcohol in the sake will be cooked away but if you really don’t want to use it, you can just add an equal amount of water instead.
Using a rice cooker is the easiest way to cook rice for donburi but if you want to cook Japanese style rice on the stove, check out my recipe here.
Adjust the sugar quantity in the recipe to taste - the original version is quite sweet.
