Jharoka chef spinning his magic

Does anyone know how this fellow does what he does? I’m talking about the Saltish Mutton Karahi at Jharoka (and Bolan, Shinwari etc.) that just melts in your mouth. It’s the stuff that will have you full and wanting more.

I was surprised not to find this Northern Pakistan specialty anywhere in Lahore or Karachi. Perhaps I didn’t look hard enough? Another selling point for the capital ;)
