Cooking a spatchcock chicken and had the grill stabilized at 350 for about an hour. When I added a pork tenderloin I didn't pay attention to the daisy wheel opening up on me. Went back to check, ten minutes later, and the temp was around 425. Everything turned out fine, however is there a quick way to bring the temps back down? I closed the bottom vent and barely had the daisy wheel open trying to get the temp down, but that's slow. Any advice will be greatly appreciated.
