Hi George
Korma is one of those dishes that has so many BIR variations. A cheap Korma tastes cheap, but a well made Korma with those extra expensive ingredients tastes totally different (even sickly for us vindaloo/phall freaks).... and you should find that a good Korma (if it uses the best ingredients), is not one of the cheapest items on the menu (and an authentic Korma is actually quite hot).
After a little bit of studying, I'm planning to magic up a Chicken Korma this weekend, but using the Saffron base (I think it's mild enough to use). I have no idea how this is going to pan out, but I will also be getting a Korma takeaway (from Saffron) to compare (and hopefully a few extra tips).
From what Raj said, they use a different base for Korma's and Passanda's - but what the hell - I'll give it a go. If Ronnac's works, I can't see why this shouldn't.
I intend using almond powder (which is not expensive), yoghurt, condensed milk (from a Carnation tin) and perhaps a bit of coconut (not sure in what form yet) and maybe a few toasted almond flakes, but just for garnish. Basically I'm going to try to replicate the BIR style.
I agree with your previous comments regarding cost. Cashews are very expensive and unlikely to be used in the dish, other than for garnish.
Pistachio nuts are also a bit of a luxury, but I have seen these in Korma recipes (not BIR though).
Double cream - well again an expensive item - unlikely to be used in the BIR cooking process. The only time I've seen cream used (and that is a tiny bit of single cream) is when they add it to the final dish before serving, with a little spiral swirl (for affect).
Should I succeed, I will keep you posted (illustrated), but it will be on the Saffron thread.
