Set up the Woodfire: Load your pellet hopper and don't forget to do the Dad Shake! Set it to Smoker/200F(93C)/and 1 Hour 5 minutes. Hit start and let it got through the ignition and preheat sequences.
Prep the Steak: While the woodfire is preheating season the steak liberally with salt, pepper, and Dad Dust (recipe in notes). Set the steak aside to let the salt penetrate.
Smoke: When the woodfire says "add food" place the steak on your elevated rack, stick a probe in it and place it in the woodfire. If you are using the XL plug the probe in and then open the app. Set it for a thermometer cook, manual, 120F(49C). If you are a 3rd part probe set it to notify you at 120F(49C). If you do not have a wireless probe be ready to check the steak in 45 minutes and then interval until it reaches temp with an instant read thermometer.
Cowboy Butter: Add all the ingredients to a bowl and mix well.
Sear: When the steak reaches 120F(49C) take it out of the woodfire along with the rack. Turn the unit off than back on and set it to Grill/HI/20 Minutes. Do not activate the Woodfire setting. Let the woodfire FULLY preheat, mine took 13 minutes. Once the unit says "Add Food" place 2 tablespoon of beef tallow on the griddle and let it melt. Put your steak down and press it down with your hand. Place a heavy object on top to ensure full contact with the griddle. Let it sear on the first side for 2 minutes. Take the weight off and flip the steak to a DIFFERENT section of the griddle and repeat the process for 2 minutes on the second side. Now sear the edges by holding the bone and moving the steak around until the edge is nicely browned, this should take about 1 minute.
Rest & Serve: Let your steak rest for 6 minutes, slice and cover in cowboy butter.
