It occurred to me that, if we can get the base sauce right, and can master the techniques for curry-making, then we can start inventing our own house specials. We can do this simply by taking a traditional Indian dish, using its spices etc, and replacing the onions garlic and ginger with our own base gravy. I would guess this is what happens in BIR's and possibly how a lot of the 'standards' originated.
Just a thought.
