Remove the steak from the fridge, and remove any packaging 30 minutes before you wish to cook it. Pat it dry with kitchen paper and leave it somewhere safe where the flies and family dog can't get to it!
Preheat your cast iron skillet until it is HOT.
Add a little oil (I used 1 teaspoon bacon grease) to lubricate the pan.
Season one side of your steak with salt, then place the salted side down into the hot pan. Season the second side once it's in the pan.
Leave for 2-4 minutes depending on the thickness of your steak. (Mine was just over 1 inch thick and I cooked it for a total of 6 minutes for the perfect medium rare finish).
Turn the steak and cook the second side.
When the steak is cooked to your liking, remove and place on a board or plate for a few minutes to rest.
Turn the heat down to low, then add the garlic, butter and rosemary to the juices already in the pan.
Gently melt the butter and stir to remove any tasty bits stuck to the bottom of the pan.
Pour the butter sauce into a small bowl or on to a plate and serve with the steak and any salads or sides you fancy.
Devour with gusto :)
