Amazing, after 3160 posts on your curry journey, you ask such a daft question about Salt. or are you simply Trolling again...
What part of the country are you in and just curious, but have you ever spent any time, in a BIR kitchen. 
Thank you for your erudite response CT :

So, in your infinite wisdom, WHY is it such a daft question and what IS the answer!?
I would REALLY like to know. Perhaps it is YOU who is trolling???

As for the part of the country I'm in, it matters not one iota (Does it? Regarding my question?). Suffice to say that I have spent MANY years eating BIR curries and MANY years trying to replicate them.
I have also been in SEVERAL BIR kitchens...as, no doubt, YOU have!
So, cut the crap and extend me the courtesy of answering my question please

Otherwise, you're adding nothing to my (or, I would assume, others') understanding!
PS: Thank you very much for reminding me why I am nowadays reluctant to participate in the forum
