It all depends... or... I'm not that picky about it. I could enjoy a hamburger that had been forgotten about and had been chared black all around.... Or , in recent times, I don't even care about char on a burger. Brats... I used to think they had to be grilled to the point where they have at least a little char on them, but I've been making them in my Davy Crocket, where there isn't even a hint of char, and they taste wonderful... Burgers are the same, I've been making mine on my Davy Crockett, turn it on at like 285F, put the burgers on, set a timer for about 30 minutes... come back in 30 minutes flip the burgers, leave for another 20 minutes or so come back and take them off the grill... Yummmmmy, with no char.
Steaks... I still prefer a nice thin layer of char... not just grill marks, but, like pan seared on a blazing hot skillet char.
Of course occasionally I do heat the PG500 up to 800F+ and slap some steaks on over top of the open flame. But honestly... I don't really do it very often, for the most part, it's unnecessary, since my frying pan will do what I really like , just fine.
Of course, tomorrow, I may change my mind.... so it really just depends on the mood I am in, or maybe even just whatever happens... sometimes surprise is good.
