Curry. I started with a recipe of David Smith (of all people) back around late 80s after returning from a couple of visits to India. I messed with the recipe for many months (using Madhur's influence) and ended up with a chicken curry which is ideal for me and mine (as was). The ingredients are now measured reasonably accurately and it turns out similar most times although the heat varies depending upon the heat of the fresh chilies (which varies considerably here).
I'd have to say curry, too. Its my first love! Though I can turn my hand to many things...
Who is David Smith? I fear that if I google that name it may not tell me much!
