When I was younger I worked as a dish dog in a local restaurant. As hard as this is to believe the Cook, an Incredibly lazy man, used to deep fry the steaks. He timed them for rare, medium, and well done. Then he would take out a grill mark branding iron He had made out of a section of grill. It had a welded on handle. He left it on top of a bed of coals so that it was always red hot. When the steak had been in the fryer the prescribed amount of time He would take it out, drain it then quickly brand grill marks on each side of the meat. It took just seconds to get the marks. The steak itself tasted like bland rubber. He just didn't care. They advertised charcoal grilled steaks. The only thing in that kitchen that saw charcoal was that branding iron. He and the boss thought that was hugely funny. I was 17 at the time and could care less in those days. Looking back I can see the giant fraud for what it was.
