Score the chicken if using drumsticks or thighs.
Add the ginger, garlic, 1 tbs of Tandoori spice blend to the yogurt in a glass bowl.
Season to taste with salt and pepper and add the juice of half a lemon.
Mix well and smother the chicken with the yogurt mixture in the glass bowl.
Cover the chicken and allow to stand in the fridge for as long as you can, preferably overnight.
Place in an oven proof dish and bake in the oven at 180 degrees for 20 mins or until the juices run clear.
Finish off under the grill turning occasionally, to get a char-grilled effect.
Garnish with chopped coriander and thinly sliced red onion (optional).
