Arrange chicken halves skin side up in one layer in a baking pan. In a bowl, mix together everything but the sesame seeds. Spread the mixture over the chicken and chill for one hour (You can freeze it at this point. Remember, if you are freezing this raw, you must use FRESH chicken, not frozen, defrosted chicken!)
Preheat oven to 325ºF. Sprinkle some sesame seeds over the chicken and bake uncovered for one hour until chicken is golden (I would say less time for chicken breasts, may have to cover loosely to avoid drying out. This sounds like it would be good grilled too!).
