i used 3 chilli powders in equal proportions (kashmiri mirch, deggi mirch and normal chilli powder). i'm not sure i need to use the posh chilli powders in this sauce in the future (i think the std will be fine).
Looks like you made the deluxe version there Jerry!

He just used the same chilli that goes into all the curries they make, so I imagine it is just standard Rajah, TRS, East End type of stuff.
I expected this to have a sour taste Jerry, does it?
Also I look forward to seeing what you use it in...keep us informed.
