I use the dometemp as a guide and grill by time. usually around 550, so the grill grates are 600++. Yes it is possible to char a steak too much on them. I have done it before. I thought hotta was mo betta! Uh no sir!
Too Hott and too much char
Got em so Hott, they all turned white
Definitely way too Hott. Burning down some mesquite wood for coals! There is no better grilled flavor in the world than perfectly aged mesquite or even post oak burned down to coals grilling a perfect steak!
