Awesome, thank you. I'll be smoking some bellies soon.I go for 180-200 on the smoker. Too high and you could start melting the fat so the goal is to get it to temp of 155 but maintain the integrity. I used to have a tough time keeping it so low in a side burner but I moved to a Weber Smokey Mountain last year and have hit the numbers even better.
Times vary, usually 4-6 hours depending on thickness. Believe it or not, Costco has pretty good pork bellies though sometimes they can be thin. I mix it up between them and a local butcher when I want something a bit thicker though theirs comes with the skin still on. The downside is remember to cut off the skin before you cure, but the benefit is you can control that top fat layer to your preference of thickness. Something to think about.
