Heat a pressure cooker. Add ghee and oil to it. When the ghee melts, add the whole spices – cinnamon, cloves, cardamom, star anise, Marathi moggu and bay leaves. When they turn fragrant, add the ground ginger-garlic-sombu paste to the cooker and fry until they brown a bit. Add a splash of hot water if the paste sticks to the bottom of the pan. Then add the sliced onions and green chillies and fry until the onions start to colour.
