Start by butterflying your roast. *See notes for YouTube video.
Add all ingredients together and marinade for 1-2 hours on the counter. This will allow your roast to marinade and temper at the same time.
Smoke at 400 degrees for 20 minutes.
Reduce heat to 325 and continue smoking for 1 hour. Check the temperature and remove when it is 5 degrees below your desired temperature. I prefer 145 for a medium rare. (160 for medium and 170 for well done)
