As I plan to make steak today, this video comes out. Timing was good.
I do agree that starting with a room temperature steak does not help with making the crust as it tends to overcook. Sous vide makes it worse. The way sous vide everything does it is by using a flame thrower, but they found that propane is the best choice as using a butane torch tended to give it a strange flavor.
If the weather holds, I'm going to try the cold steak method today.
Interesting that despite saying that resting a steak is not needed, they both still will do it.
