One thing I have noticed about the Al Frash baltis I have eaten has been a slightly coarse texture by which I mean its as if it hasn't been blended for long enough? The subtle flavours were frustratingly familiar but so far I have not been able to identify many. Cant say I have tasted any sour notes like tamarind though.
I think a lot more ginger than garlic, say 80:20? plenty of coriander powder and a small amount of turmeric. Just my tuppenth worth
The balti "Holy Grail" seems way beyond my reach.
Best of luck to you Jerry and Bengali Bob.
It seems that less is more (and i dont mean that in any derogatory way George). Im sure that when the Balti is cracked, we will all be kicking ourselves over its simplicity.
