The tamale steamer pot that the smoker is built with comes with a diffuser pan just like that that fits down near the bottom. Yes. It works very well for that.
Now that I found this perf pan fits like a glove, I have more experimenting to do- More PIZZAS!
I have seen those pots yep.. Neat.
There is a William Sonoma cast iron pizza pan I like. Only problem is it won't fit on my smoker. It has a handle.
