Cook up the bacon in a cast-iron skillet pan, long enough to render the bacon fat but not enough to crisp it. If you don’t have a cast-iron skillet, a disposable aluminum foil tray will work just as well.
Once done, remove and place on a piece of paper towel to drain and cool.
In the same pan, and using the bacon drippings, cook the chopped onion and jalapeno for 3-5 minutes to soften and the onions become translucent.
Tip in the beans, brown sugar, mustard, and molasses.
Stir the bean mixture to thoroughly combine.
Position the cooked bacon strips over the top of the mix.
Place in the smoker, beside or under whatever meat you are smoking.
