I find when I have started the fire I struggle to get the temp down to what is needed for low and slow.
I often get stuck at 350 or so.
I think it has to do with how I start the fire.
I get it really hot and then shut the holes about 80% of the way.
Is the trick to keep them shut while I am starting up and then slowly bring it to the temp I want - rather than the other way around?
Also, what is a trick to bring it down quickly? Open the egg?
