I'm late in on this thread, and its been an amusing read.
I actually agree with the notion of "nail Chicken Curry and move on from there". I get what CA is driving at.
Like a few others have noted, I personally have never tried a Chicken Curry. I understand what it is (basically a Madras minus tom puree, less chilli, etc).
And where I live, I can't just go out and get one. If I could, I wouldn't be here ;D
Madras, Vindaloo, CTM - I remember those well!
