Re: How do you do more then one coal at once?
I second (third now maybe?) splitting the quick lights and putting them on opposite sides of the bowl. It tends to give me way better heat distribution, although they do tend to burn through quicker than just a solid single disc. If this doesn't help enough, add a third half disc to the bowl, space them all out evenly. Also, make sure you pack the bowl really loosely, and a good amount of holes in the foil, in my opinion, more airflow=better. The two half disc coals should be enough for bigger smoke, be careful with adding a third. Hope this helps!
