For first marinade: Marinate the chicken in some salt, chilli powder, lemon juice and ginger garlic paste. Keep refrigerated for an hour.
For second marinade: In a bowl mix the curd and all the spices, ginger garlic paste, lemon juice, a spoon of oil. Keep it in fridge for at least 2 hours.
Preheat the oven at 200 deg c. I hv used the microwave convection. Take a baking tray and line it with silver foil.
Place a grill rack on it. Arrange the drumsticks on it. Drizzle little oil.
Cook it for 30 mins. Remove and turn the pieces.
Drizzle little oil and again cook for half an hour. The chicken will look chargrilled.
