First, I steamed it with pepper, liquor, instant bouillon (dashi) and small amount of water on a pan with a lid. After getting diminished the water, I took chicken from the pan onto a plate and boiled down the remaining broth, adding Japanese mustard (karashi), to make karashi sauce.
I place the sauce on chicken and it's done.
I ate that karashi-sauced chicken on bones, cabbage with mayonnaise and instant Japanese soup. Easy and simple but tastes good. I like them.
