Over the years, I've seen many different methods of flat grilling burgers from frozen patties to fresh even covering the burgers and punctured hole steaming. The one that's intigued me is the ball method either defrosted or fresh. Timings seem to be a ball squished slightly for a minute and then flopped for about the same. A trowel then flattens out the burger to serving size and flopped again. Can anyone expound on this method and give temps and times? I've never seen this done without some time of sauce/oil mixture being added when done. Is there a standard method applied to this that I've missed?
