Absolutely June - the only point I was trying to make was that other regions of Turkey will have authentic receipts which may, or may not be a popular as that served by Nicola and Dogan.
Mr H and I fondly remember the lovely Kartal cooking us lamb in a hole in the ground at the back of Cafe Sol because that "was the way it used to be done". He also made us a "traditional/authentic" soup which made our mouths tingle.
Authentic ? - I don't know, but as June pointed out, all that matters was that it was goregeous.
