Mix the maple syrup, miso, and sake together until the sauce is free of lumps.
2 tablespoons maple syrup, 2 tablespoons miso, 2 tablespoons sake
Heat a frying pan over medium heat, and then add the chicken pieces skin-side down. Let the chicken brown on this side (about 2 minutes).
250 grams boneless skin-on chicken thighs
Flip the chicken over and brown the second side (1.5 to 2 minutes).
Wipe as much of the fat out of the pan as possible using a waded paper towel, and then add the maple miso glaze to the pan. Turn up the heat to boil off the alcohol in the sake and caramelize the miso and maple syrup.
When the maple miso sauce is nice and thick, add the scallions and toss a few times to cook the green onions.
