oil
1 tablespoon plus 1 teaspoon Japanese soy sauce
1 tablespoon plus 1 teaspoon mirin (sweet rice wine)
¼ teaspoon granulated sugar
5 ounces boneless skinless chicken thighs, cut into about 1-inch pieces
1 teaspoon toasted sesame
2 large eggs, beaten
¼ cup very thinly sliced scallions (white and light green parts), preferably cut into long diagonal slices
1 ½ cups cooked short-grain white rice (page 33), hot
Large pinch kizame (shredded) nori or ¼ nori seaweed sheet, cut into thin strips with scissors
Combine the chicken and sesame oil in a small skillet, stir well, and set it over medium-high heat. Once the chicken begins to sizzle, cook, stirring occasionally, until the chicken is no longer pink on the outside, about 3 minutes.
Reduce the heat to medium, add the dashi mixture, and let it come to a simmer. In a steady stream, pour the eggs evenly over the chicken and sprinkle the scallions on top. Cover the skillet with a lid, leaving the lid slightly ajar. Reduce the heat to maintain a simmer and cook, shaking the pan occasionally to make sure the eggs don’t stick to the skillet, until the eggs have just fully set, 6 to 8 minutes. There will be a little liquid left in the skillet.
Spoon the rice into a shallow serving bowl. Bring the skillet to the bowl, then tilt and wiggle the skillet to slide the contents, liquid and all, onto the rice. Top with the nori. Eat right away.
