On medium heat, sprinkle a heavy frying pan with salt. No oil! Just salt. Heat. Sear steak on one side and then the other....
Flip, once or twice, or three or four times, as you wish. Cook for 15 or 20 minutes, depending on the rareness you prefer. If you want to test it, make an incision with a sharp knife and when the juices run pink, it’s definitely done.
We’re retro. Serve with ketchup!
