I'm not even sure I have reached the point where I think I know the best way--about every five years it seems I change my mind about what cut and what treatment constitutes perfection on our grill of the moment.
Got to thinking about that this morning when I watched part of an episode of Cooks Country on PBS. I quit subscribing to their publications because I eventually found their approach more tiring than illuminating so not what you'd call a fan, but it's not bad company on the teeve when you're prepping for the day's meals as I was, and today they were prepping some New York strips for grilling. Something of a money shot, that.

Crust is my current favorite focal point about grilling meat, because our new grill is so crazy hot that I can now not just aspire to but achieve real crustiness on a steak. The old one could not. Not in the 8 to 10 minutes it takes to cook a steak the warm rare we like, anyway.
They did two things to enhance crust that I've never seen done before, or considered. 1) For four steaks which had been patted dry with a paper towel, a mixture of one teaspoon each salt (probably plain old fine grain salt, though it wasn't said) and cornstarch was distributed among all eight surfaces*. 2) The steaks were then put on a rack on a sheet pan and put in the freezer for "30 to 60 minutes" to effectively "dry age" the steaks, taking advantage of the freezer's circulating, low humidity air. Best I could tell, the steaks went directly from the freezer to the grill where things went fairly normally: eight minutes for rare on their unit, lid down, turn once, pull the meat, rest five minutes.
Frankly I would quibble with them about having gone to all that trouble to build a crust, and then resting the meat under foil and on a plate (my steaks rest on a rack), both of which would soften it IMO, but that's just me.
Anyway, I look forward to trying their method. Has anyone else tested it?
FWIW, my current favorite steak: Costco prime top sirloins, which tend to be an inch and a half to two inches thick, salted and peppered both sides and allowed to sit at room temperature for an hour before going on the hot grill's searing burner. We take care of all the crusting there, then move the steaks over to the regular grill to roast at about 300-350 until the steaks are about 130 at center. I rest it about ten minutes, racked and uncovered, in the warming drawer and then slice for service. (We share one steak.)
*To my eye, that actually looked a bit scant for both ingredients. 1/8 of a teaspoon of something as finely powdered as corn starch is hard to spread around on a good sized steak, and theirs were large. Too, though it's probably politically correct for our times to be minimalistic about salt, but I would use more on steaks that thickness.
