I agree with Jeera on that one, the dishes are not quite right, for the most part but the base is very good. In fact the base I make now is inpired by both hers and Bruce Edwards'.
In my opinion, her best recipie is the Bhuna, which tastes nothing like a bhuna I've ever had, but is was an almost perfect reproduction of a jalfrazi I used to eat in a BIR in Knowle near Solihull, West Mids, when I worked up there for a while. It had the right 'spicy sausage' smell. I found the secret was deffinately to use her version of garam masala.
Interestingly, there are more similarities between her stuff and the Ashoka stuff, that everyone's raving about (thanks Panpot), than may appear at first sight! Both do not seem to use a spice mix, but contain mainly turmeric and cumin. The also both contain 'garam' type spices; in the KD case, in the garam masala; and in the Ashoka case, in the bunjara (cinamon, bay etc). I have not tried Ashoka yet, but I suspect the advantages of the Asoka method lie not so much in the base, but in the bunjarra. Apart from that I don't think there is a huge difference between the ingredients of the two. KD base is simple, no carrot or pepper, this is also similar to Ashoka if I remember correctly. Cumin goes into the Ashoka base, but into the final dishes in KD, apart from these slight differences of at what stage ingredients are added, the constituants are broadly the same......
I keep meaning to revisit KD Bhuna, but every time 'her-in-doors' and I feel like a curry, we tend to go for my -tried & tested- version of madras, which I'm reasonably happy with, just being lazy I guess!
