Pat the steaks dry with a paper towel. Let steaks come to room temperature before cooking. You can cook the steaks on a grill or in a pan.
Season the steaks well on both sides. Melt the butter in a pan. Place steaks in pan over high heat. Cook for 5 minutes on one side and flip over and cook until desired doneness. If you like your steaks medium here is how I test them. Touch the pad of skin on your hand right under your thumb. Poke that area with your other thumb. That is what a medium steak should feel like. Don't poke holes in your steaks or cut too soon. Let them rest about 5 minutes before serving.
