Luckily I had been lurking here for a while and noticed people getting better success rates using the skimmed oil. I've been putting much more than needed in the KD recipe and got about 300ml skimmed off to save

Just checked and I have everything for the Madras (will substitute chicken for Prawn).
Have printed off Bruce Edwards Guide and will make up a batch of the curry powder mix.
Going to try it today so will post results later.
And hopefully some photos.
Which would be the best forum to post my findings.
