For many years I have smoked on charcoal and loved it but recently built a refridgerator smoker and did it as gas just to keep me from having to run out there and throw charcoal on all the time. Well since I am new to gas smoking I am wondering how to get the best smoke? I currently have a gas burner on the bottom and a cast iron skillet on top of it. I soak the wood chips and put them in the skillet. My smoke was off and on and did not seem to be constant like I am used to with the charcoal smoker. What am i doing wrong? Any help would be appreciated. I swear I feel like I am starting from scratch again in the smoke department.
