Sorry if this has been discussed, but I did not see it:
I have a GOSM 3405bgw. I wanted to try smoking cheese. Read and talked to people you needed a low temp. I tried something last night that may just work when it gets a bit colder.
Start GOSM as normal. Then, slowly turn burner control clockwise from High to almost off. Play with this and you will find between 1/4 and 1/2 way in between, you will be able to maintain a very low flame. With a coffee can right on top of the burner, I was able to maintain around 110-120F. Still a bit to hgh as my cheese was getting a bit unstable. It is about 20 degrees cooler now, so I will be trying again in a few niights. Might just make it then....
Right now I am trying an electric hot plate in the bottom with chips in foil right on top of it. Temps are only hitting around 70, and smoke is flowing good.
I am a newbie, but thought I would share.
