Rub steaks with a bit of oil, and season with black pepper. Get your pan hot, put in the steaks. Turn the steaks after a couple of minutes, you should have a nice crust, turn the heat down to medium, turn again after another couple of minutes, and then turn again after that. Give them a prod as per cluckyagain's post to determine if they're cooked to your liking.
When they are - let them rest in a warm place for ten minutes. Even if they're medium to well done, they should still be juicy and tender if the meat is good, and they have been rested before eating.
Well that has to be the best steak I've ever cooked (preen)
I got the pan really hot and put the well seasoned steak in, turned them after about 4 minutes and turned the heat down a notch, gave them another 3-4 minutes and stuck pan in the pre warmed oven while I sieved potatoes and finished off the mushrooms.
Served up with a big bowl of salad, yummy!
Dh was finished his way before me and said he really enjoyed it.
