A friend of mine cooked a couple of really nice New York Strip steaks in a old fashion iron skillet and they were perfect!
All he did was put salt in the skillet and put it on the stove and got it "smoking hot" and then put the steak in and immediately covered the skillet and let them cook about a minute and a half or so and then turned them over and did the same thing. Then he took the skillet off the heat still covered and let them sit for a few minutes. They were cooked perfect! He also cooked fresh hamburger the same way and they were very juicy and fully cooked.
Try it and you will amazed.
