Cory,
Seems like you and I have been duplicating effort over the last 20 years

;D ;D
I remember a chef once telling me to fry some garlic and ginger to add into the final dish. It should be finely chopped and added just before serving.
Other flavour enhancers for the final dish include,
fresh corriander
RAW garlic and ginger puree
Cumin powder
Tandoori marinade (you know, tandoori paste with yoghurt and other stuff)
Tomato and garlic paste
I have twice managed to replicate my local take away, but was merrliy pissed and can't remember a thing about what I did (maybe a good thing).
I have never got near the restaurant's I would like to imitate.
For me it's not about cooking at home instead of going to the restaurant. The restaurant has it's place in my social and eating life, but I do eat other things

For me it is the knowledge and challenge that are important (as well as the fact that one day I may be living in a foreign country a long way from any indian restaurants, even bad ones! - there a quite a few on this site who are already in this situation.)
There are thousands of 'indain chefs' here and many of us have been into the restaurant kitchens and been shown things, but still we can't do it. Why???
If one good thing comes out of this it will be to de-mystify indian restaurant food and will likely increase the customers to their restaurants.
I say this because we had several cases here last year where BIR's were closed down by the EHO and this hit the local press on the front page. BIR's here suffered several drops in thier income after this. If they can dispel the suspicion that it is dirty or unclean techniques that produce the flavour then so much the better for them. Hiding behind a veil of secrecy is not something that is good for business. After all, what have they got to hide???
