   1                    chicken -- [3 lb]
   1                    orange
     1/3  cup           white wine vinegar
     1/4  cup           vegetable oil
   1      tablespoon    fresh thyme -- chopped
     1/4  teaspoon      black peppercorns -- coarsely cracked

Preparation:

With kitchen scissors or chef's knife, cut along each side of chicken's backbone; remove backbone and trim visible fat. Tuck wing tips behind back; flatten to 1 layer. Place in shallow casserole. Grate orange rind and squeeze out juice; mix with vinegar, oil, thyme and pepper. Pour over chicken; cover and marinate in refrigerator, turning often, for at least 4 hours or up to 24 hours. Reserving marinade, place chicken, skin side down, on greased grill over medium-low indirect heat. Add soaked wood chips. Cover and cook for 1 hour, turning and basting with marinade halfway through. Transfer to direct heat; cook for 10 minutes per side or until meat thermometer inserted in thigh registers 185F 85C. Remove to platter and tent with foil; let stand for 10 minutes before cutting into quarters.
