I have a I have a horizontal off set smoker, not vertical and fired it up to about 280º-300º with charcoal and oak split log along side for smoke, put the chicken in (on foil) and maintained the temperature for about an hour and a half. I did not keep close tabs on the time because I took it off when an instant-read thermometer read 160.
The sauce I marinated the chicken with is
4 tablespoons soy sauce
2 tablespoons sugar
2 tablespoons sesame oil
2 tablespoons sesame salt
1/4 teaspoon ground black pepper
6 cloves garlic, crushed
2 teaspoons freshly grated ginger
2 tablespoons sake or dry sherry
2 tablespoons red pepper flakes Use red pepper paste instead.
8 green onion, sliced diagonally1"
toasted sesame seeds
At the table we used a dipping sauce consisting of sesame oil and salt.
