as the title says...i have been wondering and i know ive read on here already, i just cant remember where, that ppl using cast iron pans in electric smokers. i have been thinking about doing this since i have a small cast iron pan laying around the house that doesnt get much use, and i was wondering if ppl using pans were tenting them(putting foil over top of the pan with wood chips inside) or just using them open faced with no cover and added wood chips as they went along... not sure if im making any sense, it was just a thought i had, and what better place to come for answers than the forum... also i was doing a little research on lava rocks as the little electric smoker my friend has comes with them..i generally understand how lava rocks work when it comes to heat and distribution, but my question would be could you use lava rocks in a coffee can type deal and add chunk wood thats been soaked for a bit to it,to let off smoke? or is my idea just way too far off from sanity? again im just trying to figure this out and thought id ask the people who have been doing this longer than i have. thanks in advance guys for any responses,good or bad.. look forward to hearing from yall..
