I have to agree with George. To reproduce an existing commercial brand is futile. Spend a couple of years doing it by all means, but what is the point - just buy it! (or have many hours of fun trying... depends what stage of life you are at

. Have fun with it I say)
If every BIR chef in this country has spent many years
(minutes ordering Jalpur online!) concocting a similar GM, then sending it back to Jalpur,(
then ordering back from Jalpur!) then the secrets out.........
If the GM on it's own, or Eastern star chinese curry powder :

is not the big SECRET! (Quelle surprise!), then, lets stop arguing all the time, like
my Children did all over Christmas!!!!!
Monkey see, monkey do! (It's the way MALE humans work).....
Watch it being made, make 1 yourself..... spread the word.( All from scratch!!) .......Hijack a Chef if ya can.........it's the only way.
It might be the end of the world this year, but ...lets just make one good BIR curry at home before we go!!!!!!!
Cheers
Phil
PS ..... I do not care about the chemistry of a curry, If I can make it at home .....Happy Days :-)
Edited...
Must remember which forum I'm on......others are much more ......liberal.
I sincerly apologise for the bad language.....won't happen again.
