Add the grated ginger root, garlic fish sauce, soy sauce, saki, honey and red peppers to a 8x8x2-inch dish, mixing to combine well. Add the chicken thighs, turning to coat both sides. Cover the dish with plastic wrap and refrigerate for 2 hours.

Add the oil to a large skillet set over medium heat and when it is hot but not smoking, lift the chicken thighs from the marinade, allowing the excess to drip back into the dish. Arrange the chicken thighs skin side down in the skillet. Strain the marinade through a fine mesh strainer and reserve. Discard the solids.

Brown the chicken thighs for 3-5 minutes, then turn and brown them for another 3 minutes. Transfer the browned chicken to a plate and add the reserved strained marinade and the chicken broth, stirring to blend well. Return the chicken to the skillet and bring to a boil, then reduce the heat to low and simmer, partly covered for 20-25 minutes or until an instant thermometer reads 165°F.

While the chicken is cooking, measure the rice into a mesh strainer, rinse the rice under cold water until the cloudy water becomes clear. Transfer the rinsed rice to a medium size saucepan with a tight fitting lid. Add the water and the kosher salt. Bring the saucepan to a boil, reduce the heat to low, cover the pan and simmer for about 20 minutes. Remove from the heat and allow to sit for 10 minutes. Fluff and reserve until ready to serve.

When the chicken is fully cooked, transfer them to a serving plate and cover with foil to keep warm. Bring the liquid in the skillet to a boil and cook for 5 minutes to partially reduce in volume. Adjust the heat to medium and whisk in the tahini sauce and the cornstarch/water. Cook, while continuing to whisk, for another minute or two and the sauce just coats the back of a spoon, and is a smooth light sauce.

Mound 3/4 of a cup of rice to the middle of each individual plate and arrange a chicken thigh on each mound. Spoon some of the sauce on the chicken thighs, garnish with sliced green onion and red pepper rings. Add a sprig of cilantro and a lime wedge to each plate and a side vegetable if desired.
