Steak ingredients:

  • 1.5 lbs Steak Black Onyx (Black Angus) MBS3+
  • Kosher salt to taste
  • black pepper course, freshly ground, to taste
  • Olive oil for the griddle

Whisky Butter ingredients:

  • 9 oz unsalted butter
  • 1 tbsp whisky
  • 2 tbsp brown sugar
  • ¼ tsp cayenne pepper
  • 4 garlic cloves finely chopped


  • Take the steak out of the fridge 30 minutes prior to grilling.
  • Set up BBQ for direct searing, at high heat temps of around 600°F or above.
  • Season the steak with salt and pepper.
  • Oil the hot griddle.
  • Place the steak on the hot part of the griddle, keeping the filet to the cooler or outer edge.
  • Flip the steak every minute, checking the internal temperature with an instant read thermometer.
  • Once the internal temperature reaches 141°F, remove the steak from the heat.
  • Apply a slice of compound butter to the top of the steak and let rest for 5 minutes.
  • After 5 minutes, the steaks internal temp should be a perfect 145°F medium.

For the compound butter

  • Allow the butter to come up to room temperature, or warm for a few seconds in the microwave without melting.
  • Mix all of the ingredients in a bowl, using the back of a fork to help combine ingredients.
  • Once butter is mixed thoroughly, lay it out in a line roughly 8 inches long on some cling wrap. Then roll it up and grab both ends of the cling wrap and keep winding until you have a solid log.
  • Place it in the fridge to harden up and when ready, slice off pieces to use in any dish.

To serve:

  • With mashed potatoes.
  • With steamed vegetables.
  • With hot chips.
