I just got a Traeger Timberline 850 for Father's Day, and I'm a newbie to pellet grills. Here's my question. I'm going to cook a whole chicken tonight. The recipe I have says, "Preheat your grill on 'smoke' for 4-5 minutes with the lid open. Set the temperature to high, and close the lid and preheat for an additional 10-15 minutes until it reaches 450 degrees." The Timberline 850 has a Super Smoke option that doesn't work above 225 degrees. So what do I do? Skip the "smoke" portion of the recipe and simply cook at 450? Or is there another option? Thanks.
