How long before steak is at room temperature?
According to Serious Eats, a 210 gram steak in sitting in a 21° C room managed to go from 3° C to 10° C... in 2 hours. For a larger steak going up all the way to 21 degrees, it would take longer. The take-away from that article is that it's not worth it and does not affect the resulting steak.
