Hi Stevindaloo,
If you like curries, you've come to the right place. Welcome to cr0!
I also have the KD book and have made her base several times (she's a she, BTW

). Like you'll see elsewhere on the site, you can get good results following the base recipe and her curry recipe (that's the only one other than the yeast naan recipe that I've tried from the book), but they won't be exceptional. However, if you change the way you make the final curry, the end results change dramatically. I came to this conclusion after deciding to put some of the info on this site to the test using the KD base. You can read more here if you like:

Like Mike said, don't be shy: just jump right in with any of the recipes and feel free to ask questions. Many people here have been cooking BIR-style curries for a long time (10-20yrs in some cases), so there's much collected wisdom. Personally, I'm a newbie at it, but I'm getting better results each time.

Good luck and happy currying,
ast
