I agree with Phil in that the base is only a foundation for the finished dish. It shouldn't be discernable in the finished dish, but should merely add background depth of flavour and, probably more importantly, body and texture.
Before I found this site and started trying to make BIR style curries, I used to make a Pathia-style dish from scratch. I now make the same dish and add a few ladles of base sauce and hey presto. What a difference.
Anyway, I'm off work today and not many people seem to be posting, so just thought I'd have a waffle
