Step 1

Prepare flavoured butter of your choice. Place the butter in a medium bowl, beat with a wooden spoon until creamy; stir in remaining ingredients until well combined. Place a piece of baking paper on a clean work surface. Place butter in the centre and form a log (approximately 4cm x 12cm); wrap up tightly twisting the ends. Refrigerate while preparing the steak, or up to one week in the fridge or one month in the freezer.

Step 2

To prepare the steak, 1-2 hours before cooking use paper towel to blot any excess moisture from the steak. Season generously on both sides with salt and pepper. Return to the fridge, uncovered.

Step 3

Thirty minutes before cooking, remove the steak from the fridge and allow to come to room temperature. Preheat a barbecue to high heat. Just before cooking, drizzle steaks on both sides with the oil. Place on a hot grill, so hot it should sizzle; cook for 2-5 minutes on each side or until done to your liking (see Test Kitchen tip). Transfer to a plate, top with two slices of flavoured butter and cover loosely with foil; leave to rest for 10 minutes.

Step 4

Serve steak sliced on a platter with sides of your choice.
