Makin' bacon was 90% research, 10% execution, the former focused on the "cure".
There's quite a few recipes out there that call for salt, sugar, syrup, nitrites, nitrates, etc etc. Nitrites are used extensively to ward off botulism and to give the bacon its characteristic pink color. For me, I just used loads of kosher salt and brown sugar, coated the pork bellies well, wrapped them in plastic, and let sit / cure in the fridge for a week.
You're supposed to then remove from wrap, rinse, and air dry in the fridge for another day to let the skin form a "pellicle" - an exterior that facilitates the uptake of smoke. I did not do this, b/c I was impatient to get smoking. Next time I will.
Re: smoking, people smoke bacon at sub-100F for days or @ 200F for just a couple hours. I smoked mine in a green egg @ 200F for 2.5 hours. Next time, it'll be lower, longer as I wasn't fully satisfied with smoke penetration. Lastly, pretty much all recipes agree on a finished 150F internal temp.
At this point, the bacon is still not cooked, as you need to fry / bake / etc up. I cut off the skin and sliced the strips into bacon, then fried 'em up on a cast iron pan with a iron press.
It was good, not awesomely good, but still pretty good. It's more like bacon jerky than the traditional *snappy* bacon from Farmer Johns. Because of its strong flavor, my bacon is ideal on a wheat bread BLT as it stands up to the nuttiness of the wheat.
I love pork. The pig is a magical animal.
Here's a pig roast I did a couple months back.
