You will continued cooking the steak for an additional two minutes. Most importantly you want to admire just how beautiful that steak is looking now. Notice the deep brown (not black) color of the cooked surface now staring up at you. Beautiful, isn't it.
Again, be patient and let the steak continue (burner still on high) for two more minutes. During this time, make sure you have your grill (or oven) mitt on. This needs to be a good mitt, since the metal you are about to pick up is about 500 degrees F. and heavy.
