Hi, and thanks for the welcome messages.
I have looked at some of the suggested base recipes and now look forward to trying some real alternatives to the Kris Dhillons version.

The debate about the base or the final recipe having the secret is indeed fascinating, but unfortunately I have no evidence either way.
I/we do however in the main prefer Bangladesh style curry, then Indian style, and lastly Pakistan style. Anyone else have opinions, and how much does the bases for these different styles vary do you think?
Fantastic site!
Eric
