Keep the steak in the fridge overnight uncovered
Cook to desired doneness. It was about 6 minutes per side for medium rare
Remove the steak from the heat into a deep dish pan or a container deep enough for the steak. While the steak is resting, use the Breville smoking gun to infuse smoke flavour into the meat
Add hickory smoke chips to the wood chamber of the Breville Smoking Gun. Place the silicone hose under the plastic wrap with the opening above the steak (making sure the hose does not touch the steak)
Turn the smoking gun on high speed (double line) and ignite the wood chips. Switch to low speed (single line) until the pan is filled with smoke, then turn off the smoking gun. Let the smoke infuse for 3 mins. Make sure the plastic wrap tightly seals the pan so the smoke does not escape. Feel free to remove the hose before sealing the pan. I left my hose in while the smoke was infusing the meat
After the 3 minutes, remove the plastic wrap and place the steak in a dish to be served
For the steak spice, I used a Canadian brand called 'Wicked Gourmet'. Ingredients include spices, salt, dehydrated garlic, canola oil, dehydrated onion, natural colour (No MSG, fillers and is gluten-free).
The timing of the steak is a guideline as it depends on the thickness of your steak, the equipment that you have, and other factors.
