Defrost the steaks by placing them into a bowl of cool water (still in their packaging). They should thaw in less than 10 minutes. Once thawed, remove the steaks from their packaging and dry them all over using a kitchen towel. Season well with good quality pure Sea Salt.
Take a cast iron pan and heat it until it is very hot. Do not add any oil to the meat or the pan.
Place the steak in the pan and cook for one minute. Turn over and cook on the other side for a further minute, until the juices start to appear on the surface.
Turn over and cook for two and half minutes, flipping over onto each side (you could add butter and herbs at this stage and baste).
The cooking time should be five minutes in total.
Rest uncovered for at least five minutes - be patient as this bit is key.
