Indian Chicken

Indian chicken is one of the things I have been cooking forever. I f0und it in an old copy of the New York Times Cook Book and we hit it off right away. I sometimes like to have soy sauce on the table when I serve this, because...well it tastes good. Nobody else likes it that way...just saying...
