In a pot, fry the onions slightly dark brown in the cooking oil. Add dhania powder, cumin powder, red chilli powder, haldi, salt, yoghurt, ginger and garlic paste. Fry this masala for few minutes. Add the mince and fry for another 5-10 minutes until the water that releases from the mince is almost dried. Now add approximately 1 cup water and cover and cook till the mince is soft. Simmer on low medium heat. This should take about 20-25 minutes if using chicken mince but about 20 more minutes if using mutton.
