Some people may not like this but:
I strongly urge the members of this forum to forget the whole idea that 'this can't be done at home'. - I know it is a great excuse every time your NOT overjoyed with the curry you've just cooked. But it simply CANNOT be true. Sure, all the BIR chefs and bosses would love us to think that - and I don't blame them at all, it's their livelyhood.
As long as we accept this (that it can't be done at home) rubbish, we will be hampered continually, because there's always that excuse for failure, when the truth is that we still have a bit of work to do yet.
My curries have improved dramatically since this forum started. If that correlation continues, then I will be even better at some time in the future.(logic)

Oh by the way, can someone give me one(or more) good reason why, I would tell you excactly how to cook something at home - which I continually charge you ?7 for?
