I agree there's great mileage in trying changes, reporting back, debating, etc. Your changes are all worthwhile and interesting to hear about (brilliant photos too) but I just think it makes the end result different. It may be better or worse but the end result will probably be different to Darth's originals. And as he described them as 100%, no doubt tried, tested and tweaked to near-perfection, I reckon we should all try the original recipes first and only make changes next time round and subsequently. Hold back a test sample of the original to compare with further developments.

I share your view that quantity change (e.g. to half or quarter measures, pro-rata, throughout) will have little effect. But I may be wrong because others reckon it does! Greater oil may be popular in many BIRs but Darth says his favourite local BIR uses less oil. So the whole recipe has been balanced to work "100%" with less oil. If you change one significant thing like oil, I think you move into the 'unknown' even if it is better. Another simple example, if you like cakes: A Victoria sponge cake has equal quantities of butter, sugar, eggs and flour. It has a characteristic texture and taste. If you increase the flour by 50% but leave everything else pretty much the same, it turns the cake into a Madeira cake, which has a quite different texture and overall feel. I like both but they are different.

I know this is what many people say and you may all be right. Also, your extra fat probably meant most of the water boiled off and it turned into a gentle fry-up. Again, I feel this may produce a different result, even if it was better. Also, I just checked some recipe books for stews, soups and other dishes using onions, carrots and celery. It's a popular mix. All these vegetables cook (boil/simmer) in about 20 minutes or less. So perhaps Terry is right about half an hour being more than enough cooking. Darth says to check the vegetables are cooked after 1 hour. I see no way they won't be cooked. Who says an over-cooked mush is better than a puree of perfectly cooked onions, celery, carrots and other vegetables? You cooked them for about 180 minutes. I'm going to try cooking for less and less time (e.g. 20 minutes) to see what the impact is. A 10 or 20 minute carrot, eaten as a vegetable, can have nice flavour. A carrot cooked for even 30 minutes will be tasteless and over-cooked, like some of the worst canteen food. Maybe there's a lesson there.

I agree. I looked at Rajah hot vs mild on the Asda shelf. All the ingredients were the same apart from the addition of chilli powder to the 'hot' version. So I reckon the mild version is the one to buy even if you like red hot curries.

I agree it is standard practice to fry spices for a few minutes to get rid of the 'raw' flavour. Many books says it's a vital stage. But Darth's Madras (stage 3) recipe adds a lot of raw spices without any frying and it turned out delicious for me. I have other recipes where that 'raw' approach has worked well too. So who says spices need to be fried or roasted first? Again, I guess this may have made your end result different even if it was better.
