This may cause a bit of controversy and i know some have been behind the scenes of a bir kitchen, although there are lots of youtube clips from bir's, theres nothing like publicity, publicity can make you money, get you noticed, although ive been into 3 or 4 bir kitchens and watched them cook my takeaway they seemed very reluctant to really tell me anything when i asked a question or two, so do we really know what goes on behind closed doors, maybe the whole cooking method is different, a way of leading us down the wrong avenue to stop us getting it right! or maybe someone as witnessed all the goodies going in the pot, if that was the true case then we would have captured that true authentic taste long ago that everyone is longing for, after reading a few past threads its seems a lot of budding bir chefs on here have gone to the ends of the earth to get it but still no luck in doing so, just a thought!!! maybe you can see my point!
