Pete,
I fully agree with you. But maybe we are looking too hard at this, thanks to you and the others on this site, I can now cook a curry that as far as my friends tell me is as good and if not better than some take-aways.
I have had indian meals that have been good, some places have been ok, and some very mediocre. Some weeks even my fav place turns out a crap curry.
On Saturday uk food (sat channel) showed the one hour special narrated by neil morrisey about uk's love of indian food, in it was an indian chef in an indian restaraunt standing at the cooker, infront of him was one big pot of sauce and a wok.
He took a big ladle of sauce, and by god it looked just like pete's 600mil oil curry sauce, although more oily and started cooking it, no massive heat or flames.
And some chefs on it even admitted the use of one base sauce to cook all dishes (no surprises there).
But I do agree with you Pete and Ghanna and the others (alright Darth) that there maybe something we are missing, but I don't think we can do it in our own homes, and I really believe that what the owners of these places are telling us is true, there is no special stuff, no magic, no secret, but just skill, and lots of experience.
I can put on my CV 15 years experience of working in IT ( and thats 8 hours plus a day five days a week). Now tell me you can say that you have 15 years experience cooking curries six days a week 8 hours a day.
Tell you what, lets all meet up for a top class curry somewhere have a few beers and kidnap the chef, cue music "stuck in the middle with you, jokers to left of me clowns to the right, here I'am".
Keep it up we may crack it yet.
