Hi
My personal pecking order is, as of right now:
(1)
Abdul's book - learn2cook vol 1
Abdul's other recipes (at cr0)
Personally, Abduls base and 8 spice is the closest to the BIR taste that I seek, that I have ever consistently created at home before ever.
(2)
Kushi Balti
I recommend this book, as I find the exotic taste of this chaps BIR / Balti style to be magnificent.
If I lost all my books, these are the ones I would replace first as of Jan 2012.
Edit: Although I should say, I continually refer to ChewyTikka, CBM, CA.
Thanks
