Heat cooking oil in saucepan and cook onion and garlic until tender, but do
not brown. Add ketchup, stir, and add remaining ingredients (EXCEPT
CHICKEN). Bring to a boil. Reduce heat, simmer, uncovered, for 10
minutes, stirring occasionally. Set sauce aside.

Season chicken pieces with additional salt, if desired. Place chicken
pieces bone side down over medium to hot coals. Grill 25 minutes (until
bone side is well browned). Turn pieces over and grill 25 minutes more,
until chicken is tender. Brush chicken frequently with sauce during last
10 minutes of grilling, using all the sauce.
