In the same pan, over medium heat throw in the bay leaf, cumin seeds, onions, tomatoes, chilis, cashews, ginger and garlic. Add a cup of hot water, cover and cook until the onions and tomatoes are throughly cooked
Drain, remove in a bowl to cool it down (reserve the stock as well). Once cooled, discard the bay leaf and grind rest of the ingredients to a fine, smooth paste, without adding any water
Re-heat the same pan and add this paste, along with the kasuri methi, garam masala, salt and chili powder. Mix well and cook over medium low heat for 5-7 minutes. Use the reserved stock to thin down the curry, if needed
Add the tikkas in the masala, stir them in gently, simmer for another 5 minutes and remove from flame. Garnish with coriander leaves and serve with buttered naan. Enjoy!
