The dopiaza is a classic Indian dish dating back at least to Moghul times. The name "dopiaza" broadly translates as "2 onions" or "double onions". Some traditional versions of the dopiaza use twice the weight of onions compared to the weight of meat but a classic Indian dopiaza is more likely to use the onions in 2 different ways, fried and boiled, at different stages of the cooking. It is made medium hot. and is usually served with an Indian flat bread like Naan or Roti.
Dopiaza dishes are usually made with either chicken or lamb. You can get dopiaza ready sauces on the internet.
