Grind green chillies, 6 cloves, and ginger into a smooth paste. Keep aside.
Heat ghee and oil in a pressure cooker. Add bay leaf, fennel seeds, cinnamon, cardamom, and cloves. Let them splutter.
Add sliced onions and sauté until 80% cooked. Do not brown too much to maintain the white color.
Add the ground paste, mint leaves, and coriander leaves. Sauté for 2 minutes until aromatic.
Add cleaned chicken and mix well.
Add coriander powder, garam masala, and salt. Mix thoroughly.
Pour in coconut milk (total 1.5 cups liquid for 1 cup rice). Let it come to a rolling boil.
Add the roughly chopped tomato. Do not sauté. Let it boil directly in the coconut milk mixture.
Add soaked and drained raw rice. Mix gently.
Allow it to boil for 5 minutes.
Close the lid and pressure cook for 1 whistle on medium flame or keep it for 10 minutes on very low flame and switch off.
Let the pressure release naturally. Fluff gently and serve hot.
