Season Beef Tenderloin Roast generously with salt and pepper.
Lightly coat grates with vegetable oil spray. Close cooking chamber lids.
Place 3-5 lbs. of charcoal, in center of the firebox. Open the firebox air vent approximately 1-2″, and smokestack damper halfway. With firebox lid open, stand back, carefully light charcoal and allow to burn until covered with a light ash. (Approximately 20 minutes)
Once coals have ashed over, add wood chunks. Do not shut firebox lid until the smoke is clean, often called Blue Smoke.
Close firebox lid. Adjust the firebox air vent and smokestack damper to regulate cooking temperature. The ideal smoking temperature is 300°F.
