Mix together your Kasu, Light Soy Sauce, and just enough Sake or water to make a thick spreadable paste. How much Sake or water you need depends on your Kasu.
Score your chicken thighs skin so that the marinade can penetrate to the meat below it.
Spread half your marinade on one side. Move the chicken thighs to a bowl or covered container and place them marinade side down, Spread the remaining marinade on the other side so that both sides are fully covered.
Marinate for at least 4 hours.
Heat a large skillet over medium heat and add olive oil. Once hot add chicken thighs skin side down, and cook for 10 minutes. Flip chicken thighs and cook for another 7-10 minutes or until chicken is cooked through. The marinade may char a little due to the sugars in the Sake Kasu. Let cool on a cutting board for a few minutes. Slice meat off of the bone and dispose of bone and chicken skin.
Serve with Rice, Miso Soup, and Pickled Veggies.
