Hi fellow smokers...Just wondering, on an Electric Smoker (LIke the Gourmet Electric ECB), how long should I pre heat? 15 mins...30mins...60,ins? When should I add the wood? Do I or dont I need the water bowl filled? I was able to buy an "inline" fan speed control (kinda like a 20 dollar rheostat) and "control the temperature". I want to test it with 2 pork steaks (typical st louis an ) on a reverse sear to day. any assistance would be grateful.
