Recipe Tips

• Room Temperature Steaks – Before smoking meat, you want to make sure they come to room temperature. We usually set out about 20 minutes before smoking.
• Meat Thermometer – Anytime you smoke or cook meat, always use a meat thermometer to ensure the steak is cooked.
• Rest Steaks – Once you remove the steak from the smoker allow it to rest on a cutting board. We recommend covering with aluminum foil to keep warm. This allows the juices to marinate in the steak for the best flavor. We recommend to allow steak to rest for about 30 minutes.
• Slicing Steak – Slice the steak about an 1 inch thick slices to serve with your favorite side dishes.
