With fishing season around the corner and a lake near by that stocks Landlocked Salmon, I'm interested in learning how to cold smoke. I've got a Brinmann electric smoker that generally runs around 225-240 (depending on the temperature outside). I've also got a Brinkmann Gas / Charcoal Combo grill with the ability to use as a smoker. I haven't tried smoking on the charcoal yet, but I've done plenty of chicken and ribs on my electric smoker. My question is, is it possible to cold smoke on either one of these? If so, how do I go about doing it? Thanks!!
