Hopefully a simple one this: went out to a local Indian yesterday, was about to go for my usual Bhuna  and tried something new for a change - it was great.  It then occurred to me that I didn't really know what all the "British classics" are all about anyway, so my question is, is there anywhere which sets out whatever consensus there is as to what constitutes a "tikka masala", a rogan josh, a bhuna, a balti et al?  I honestly couldn't tell you what makes those dishes what they are off the top of my head and I'd really like to know more...

Thanks!
