This video is a demonstration of how to cook a perfect steak. She explains how to sear a steak in a cast iron skillet. She turns the burner on pretty high. She explains that a non-stick pan doesn't work well for this recipe, because a cast iron skillet is better for high heat. She uses a rib eye steak and takes it out of the fridge 20 minutes before cooking so it won't be cold when it goes into the pan. She sprinkles the steak with salt, and freshly ground pepper. She puts unsalted butter into the hot pan, and when it's melted, puts the steak into the pan. Get a different plate to put the finished steak on a different plate, and warm it first. Don't nudge or squish the steak while it's cooking. To make a medium rare steak, let it cook on one side for about two minutes until it's nicely caramelized. Turn it only once. Use a meat thermometer and cook the steak until it's about 110 degrees in the center for medium rare. Let the meat rest for about five minutes after it's done cooking so all the juices will stay in the meat. This is a simple demonstration of the correct way to cook a steak.
