I can't say what "most other members" on this site are trying to reproduce (though others on here clearly think they can). I won't even try to speak for others until I have tasted their cooking, which is different from trying their recipes. Other people can speak for their own standards.
I am not setting myself up as an expert or saying that saying my curries are any better or worse than anyone else here. All I can say is I think my curries taste damn good, and I do not regard them as sub standard.
Take the Ashoka thread for example. This was quite a busy item and a few of us (including me) tried the base, bunjara etc. It tasted superb and certainly not sub-standard. Even though I agree that many takeaways produce a fairly uninspiring product that doesn't mean most members are aiming for the same. I think we need to try and avoid huge generalisations here.
Let's face it if you are going to try and produce a gourmet burger you wouldn't take McDonalds as your benchmark. As long as I can produce damn good tasting curries I will be a happy curry eater and I am always on the look out for new recipes and techniques here. One of the good things about this site is that there is enthusiasm and ideas aplenty, which I regard as far from sub-standard.
