6 | tablespoons dashi (1/4 tsp instant + 6 tbsp water) |
2 | tablespoons dry sake |
2 | tablespoons mirin or aji mirin |
2 | tablespoons soy sauce |
½ | teaspoons sugar |
2 | skin-on chicken thighs, deboned (do it yourself or ask your butcher) |
1 | small onion, thinly sliced, lengthwise |
4 | eggs |
6 | sprigs of mitsuba, cut into 1-inch lengths, or 2 scallions, very thinly sliced on a sharp diagonal |
Short-grained white rice (often labeled sushi rice), cooked, for serving |
Make the sauce: In a small bowl, combine dashi, sake, mirin, soy sauce and sugar; stir to dissolve sugar. Set aside.
Heat a small (6- or 7-inch) nonstick (or well-seasoned carbon steel) slope-sided skillet over medium-high heat. Brown the skin side of each piece of chicken until crisp, 3 to 4 minutes (meat will still be mostly raw). Transfer to a cutting board, skin-side down. Dice into 1 to 1 1/2-inch pieces.
Cook chicken and egg in two batches: In a small bowl, beat eggs until yolks and whites are broken, but still distinct. Return skillet to medium-high heat, wiping out any excess grease. Add the sliced onions and the sauce, and simmer for 1 to 2 minutes, until onions just begin to soften. Add the cut-up chicken; simmer for another 1 to 3 minutes, stirring, until chicken is white on the outside.
Pour about half of the beaten eggs around the pan; let cook undisturbed for 30 seconds. Add the rest of the beaten eggs, and the mitsuba or scallion. Adjust heat to low, and cook 20 seconds longer. Cover pan with a lid or foil and remove from heat. After a minute, uncover pan; eggs should be wobbly, but not raw (if they need more cooking, return the covered pan briefly to the heat).
Carefully slide egg, chicken and sauce onto a bowl of cooked rice, trying to keep the mixture from flipping over. Serve with shichimi togarashi, if desired.
