Hi All, New to smoking here. I have only done it about three times now. I have a propane smoker (Masterbuilt 30" Propane Smoker) and I find that when I try and keep the temp at 250 degrees (for smoking ribs), I don't get much smoke generation. I am using a cast iron skillet, that I put on top of the wood chips stand that came with the smoker, to hold my wood chips. Questions #1 - Is it the heat from the gas burner that is cooking the meat or is it the smoke? Question #2 - Should my smoker be producing a lot of visible smoke? I tend to see much more smoke with higher temperatures, however, most recipes call for low heat (250 degrees) Questions #3 - Should the wood I am using for smoking become black and charred after a while? I know, probably a stupid question, but I have not read how the wood should look if it is burning properly. Question #4 - Should I be spraying the wood with water periodically? Thank you so much for any assistance!
