Pete i believe in KD base.. also youll notice that when you add to the base and blend down it changes the consistency away from the BIR, although if you add water to the base it gets closer again.
Its odd i know, but i really believe KD?s base is the base to use, just something that needs to be added
i know that black pepper is used and black pepper can also have an effect of reducing some spices
could be an anwser why restaurant curries taste simular?
To those who haven?t tried KD base looks here ->

I believe this is one of the answers.
I think restaurants can reduce sauces alot quicker than we can
