I asked to buy oil, or anything they could offer, to get that taste, and they said there is nothing to sell to help with that. they said its all about preperation, technique, and a life time of erradicating certain flavors in a curry and improving the good flavors bit by bit over many years. i believe this. i have seen their oil, and it is just veg oil. i have purchased there base, and it is a very plain greenish veg stock with virtually no spice.
Derek,
So you have plain (unseasoned?) vegetable oil. The base is like a "very plain...vegetable stock". And the "secret" is supposedly in the "preparation, technique and a lifetime of......"??
Well, as far as I can see, cooking curries (i.e. "the technique") is a question of:
- sequence (i.e. of adding the ingredients)
- time (how long you cook things for)
- temperature (what temperature you cook them at)
And, for the life of me, I cannot see how any of this (from observing practices in restaurants and restaurant videos, etc) creates the "taste" or the "smell" of a good BIR curry!!!
Furthermore, I have seen NOTHING that requires umpteen years of training in order to produce it!! :

So what do you (and CK) think are the the important issues regarding the so called "techiques"

Nobody has, yet, seemed able to define it!??
From what I can tell, "technique" generally involves frying some garlic, ginger, tomato paste, some basic spices, curry base and pre-cooked meat, in some defined sequence (for some time and at some temperature) and, "hey presto!", I have the "taste" and "smell"!
I would be REALLY interested in hearing more about about these so-called "techniques"
