A recipe for Koftay Gravy

Re: A recipe for Koftay Gravy

This is something i am struggling all my life with:(

This time i ground browned onions along with yogurt and tomato paste along with the masalas and then cooked this paste along with fried meatballs. It turned out good but didnt have the killer punch i wanted:(

Some one please share the recipe for reddish and also the brownish gravy:(
