I think the sweet spot on the SM066 is 250. When I smoked my fattys on there at 275 they were great with a lot smoke. Same thing with the shotgun shells. I noticed at 225 there was a ton of moisture.
Next is Salmon. I have a recipe that calls for smoking at 150 for one hour and then 175 for the final two. I have the cold smoke baffle. Is 175 too hot for that use?
