Thank you all, especially for that pdf, I feel the anxiety lifting somewhat. I am especially interested in recreating BIR, the motivation being I have moved home near to Calne and there is only one local BIR and sadly not up to my expectations.
Some of the advice is counter intuitive to me (the curry base), but its logical, how else could a curry be turned around so quickly?
I have brought Rajah spice packets in the past are these adequate? My concern in buying spice is that if you get an older packet (as in supermarkets) the potency tends to decrease substantially. I will be looking around the Swindon area to source ingredients.
Anyone have any thoughts on how to avoid nose fatigue? Obviously I will be monitoring my curry intensively but am wary of the fact that over exposure to it will spoil the taste.
On a side, I'm also quite fond of Thai green curry and have had reasonable success in recreating although the approach is very different (all about FRESH), I order my ingredients "fresh" online.
