Because our donabe (Japanese claypot) is too small to cook a meal for four, my chicken rice was cooked in a cast iron pan. Chinese sausage, mushrooms and bok choy complete the dish.
Cut each bunch of bok choy into halves vertically and rinse to remove and silt trapped between the stalks.
Parboil the rice
Spread the rice on thick-bottomed pan.
Pour in the chicken broth and mushroom soaking water.
Cover and cook the rice just until the liquids have been absorbed.
Brown the chicken
Take the chicken out of the fridge and toss with the corn starch. Shake off the excess.
In a wok or frying pan, heat enough cooking oil to reach a depth of at least three inches.
Brown the chicken, in batches if necessary, until a light crust forms on the surface (you're not cooking the chicken all the way through at this point).
Make the sauce
Pour off the oil in the pan leaving only a tablespoonful.
Saute the onion and garlic just until softened.
Add the chicken and cook, tossing, for a minute.
Pour in the soy sauce and sprinkle in the brown sugar.
Add the oyster sauce and cook, tossing, until the sugar is completely dissolved.
Arrange the bok choy on the side opposite the chicken.
Pour half a cup of water along the edge of the pan.
Cover the pan tightly and, with the heat set on low, cook everything together until the rice fully cooked (the chicken should be fully cooked too at this point).
Serve
Ladle rice, chicken, sausage slices, mushrooms and bok choy into bowls and serve.
