Phil i really have to disagree. i purchased her original book and made many curries, none came close to bir. in fact they tasted rather odd. When i compared them to some of the wonderful traditional indian recipes i was making at the time (from other books) i concluded kris dillon had no real mastery of the art of bir cooking. If someone writes a book on a subject and it does not deliver the goods, it is a strong indication that their underlying knowledge is lacking. Surely someone with a long heritage behind them would have no problem writing a book which at least manages to replicate a few key bir dishes eg madras, or rogan josh or tikka masalla. all of these recipes from the original book were nothing like a real bir dish. So i am unclear why you feel she has some long heritage of bir cookery knowledge. I am of the opinion kris is more of a business women/author/casual cook, with links in the cookery business. The kd books are a clever money spinner, but i see little evidence of a wealth of heritage and cooking knowledge passed through generations. Even the kd base needs modifying to become acceptable. I would be more forgiving if just one recipe in that book stood the test of time. but alas on closer inspection none of those recipes are special , and part of my favourite repetoire. Explain what you mean by punjabi heritage? do you mean cooking knowlege ? where is the evidence of this cookery knowledge kris has from this heritage?
