What sort of curry do you like Derek? There are lot's of main curry recipes on this site which can be used with almost any base sauce, the KD is very versatile so you could go for anything on on here. There is quite a bit of debate on here also regards to mixing and matching base and curry recipes although I think most people would agree that the KD base is good, the curry recipes are way of the mark.
I agree with BB, I have tried and failed to make a healthy curry and it just doesn't work if you want to get close to a BIR. Better to maintain a balanced diet and not eat curry every night of the week, thats easier said than done though
