So building on the colander question.... I ran across one of these:
The description says it is 11" in diameter (not sure if that is opened or closed).
Thinking that it may allow it to diffuse some of the central heat plume to the outside, and still let grease to drip through and the flavor to waft up. I figure for $11 I may give it a go, and then do some temp reading to see how things balance out on a newer drum I am building. I figure it will need a very low rack to sit on.
Comments? Thoughts? Pitch Forks and Flaming Torches?
