Take the steak out of the fridge to get to room temperature for 30-40 minutes. Oil the steaks on both sides.
Take a pan to smoking hot temperature then sear the steaks for 1 minute and then turn the temperature down to medium and cook for 2 minutes.
Flip and salt the steak. Turn temperature up and sear for 1 minute. Turn temperature to medium and cook for 2 minutes.
Now put a heaped tablespoon of butter, with herbs and garlic if you desire then baste the steak. Leave to rest on warm plate or in foil parcel for 5-6 minutes.
If your steaks are thinner, reduce cooking time.
For the chimichurri chop the pepper, parsley, oregano and shallot, finely, mince the garlic. Now add oil and vinegar until it's a sauce that can fall off a spoon. Add the cayenne and honey to taste.
Serve with some new potatoes or whatever you fancy.
