Marinate chicken in curd mixture for 3 to 24 hrs, depending on your time. The longer the better, because chicken will absorb flavors of marinade better.
Rub the wire rack of the oven with oil and place the marinated chicken on it, so that the extra marinade can drip down from the grill.
Grill for 15 mins in the oven at 180 C.
Overturn again, brush with little oil and grill for another 15 mins or till tender n crisp.
