Pat the chicken thighs very dry. Lightly score any thick or uneven areas so they cook evenly, then season with kosher salt. Place the chicken skin-side up on a plate or rack and refrigerate uncovered for at least 45 minutes, or up to overnight, to help the skin dry and crisp.



Make the teriyaki sauce by combining the sake, soy sauce, mirin, brown sugar, honey, smashed garlic, ginger, and orange juice in a small saucepan. Simmer for 5 minutes, then whisk the cornstarch with water and stir it into the sauce. Cook until lightly thickened, strain out the aromatics, and set aside.



Heat the avocado oil in a large skillet over medium heat. Add the chicken skin-side down, then place a piece of parchment or foil on top and weigh it down with another pan or a heavy lid. Cook for about 6 minutes, until the skin is deep golden and crisp.


Remove the weight, flip the chicken, and cook for 1 to 2 minutes more, or until the thickest part reaches 175°F. Transfer to a cutting board and let rest for 5 minutes.


While the chicken rests, quickly cook the bok choy in the same pan with a splash of water and a pinch of salt until just tender. Slice the chicken skin-side down to keep the crisp skin intact, then serve over hot sushi rice with bok choy, teriyaki sauce, and toasted sesame seeds.
