In a shallow dish or zip-top bag, combine sugar, soy sauce, dry sherry, sesame oil, pressed garlic, and grated ginger.

Add chicken pieces to the marinade.

Cover or seal the dish/bag and chill for 30 minutes, turning occasionally to ensure even marination.

Remove chicken from the marinade and discard the used marinade.

Thread the marinated chicken pieces onto skewers.

Sprinkle sesame seeds generously over the chicken skewers.

Arrange the skewers on a lightly greased jellyroll pan.

Broil the skewers 3 inches from the heat (with the electric oven door partially open) for about 5 minutes on each side.

Cook until the chicken is cooked through and the sesame seeds are toasted.

Serve immediately.
