Dopiaza/Dupiaza/Do Peeaza

A traditional Mogul dish, the term means any meats cooked with vegetables. The dish found in restaurants today in the west uses two kinds of onions or the same amount of onions as the meat. Hence coming from the name which sounds like two onions. Is this another recipe that has been created by our chefs in the Midlands or is it a true dish? Cooking with the same amounts of onions and meats can make a dish very sweet, so my opinion would be to use two onions in the different stages of cooking, i.e. adding fried brown onions on top, just before serving.
