Add yoghurt and mayonnaise in a bowl and whisk well.
Add all the other ingredients except the chicken and mix well.
Drop in the chicken into it and mix. Let it marinate for 2 hours or overnight.
Soak bamboo skewers in water for half an hour. Skewer the chicken into it.
In a pan, pour a little bit of oil and spread well. Shallow fry the chicken until cooked and charred on all sides.
The kebabs are ready.
You can infuse the kebabs with charcoal smoke too. For that place the kebabs in a plate and make space in the middle for a small steel bowl. Place the steal bowl there. Next heat up the charcoal until it turns red. With a help of a tong place the charcoal in the bowl and immediately add a tbsp of ghee into it. Cover the place with a lid tightly making sure there are no gaps so that the steam doesnt escape. Let it sit for 10-15 minutes. The kebas will get a tandoor smoky flavor this way.
