Be sure the steak is it room temperature when you start to cook
Preheat the oven to 500°
Use a cast iron skillet/fajita plate
Put a spoonful of ghee on the skillet before you heat it up
Heat the cast-iron skillet/fajita plate on the stove top as hot as you can get the flame.
Rub the steak generously with ghee, salt-and-pepper only
Place the steak on the skillet/fajita plate according to the f following formula
Flip the steak and place in the oven according to the following formula
Serve the steak on the skillet/fajita plate and it will stay hot until the last bite. My soul doing, the steak will start at a little above rare and continue to cook TO medium rare
THE SECRET FORMULA
MEASURE THE THICKNESS OF YOUR STEAK
MULTIPLY THE THICKNESS BY 1.5
THEN, TAKE THIS CALCULATION AND USE IT FOR TIME ON THE BURNER AND TIME IN THE OVEN
FOR EXAMPLE, A 2 INCH STEAK TIMES 1 ½ EQUALS THREE. THEREFORE, THREE MINUTES ON THE RED HOT SKILLET ON THE STOVE TOP, FLIP THE STEAK AND PUT IT IN THE 500° OVEN FOR ANOTHER THREE MINUTES.
