How to Make It
Remove and discard skin and breast bone from turkey. Place breast halves in a jumbo, heavy-duty, zip-top plastic bag; set aside.
Combine orange juice and next 6 ingredients in a jar; close tightly, and shake vigorously. Set 1/2 cup marinade in refrigerator. Pour remaining marinade over turkey; seal bag. Chill 8 hours, turning bag occasionally.
Remove turkey from marinade; discard marinade.
Cook turkey, covered with grill lid, over hot coals (400° to 500°) for 18 minutes on each side or until a meat thermometer registers 170°, brushing occasionally with reserved marinade. Let stand 10 minutes before slicing.
To cook turkey in oven, place on a rack in a roasting pan; bake at 325° for 1 hour and 10 minutes or until meat thermometer registers 170°, brushing turkey occasionally with reserved marinade.
