I use off the shelf(Sweet Baby Ray's Honey Chipotle)as a base only then add some of the juices from the ribs, a little honey and a couple drops of habanero, and some pulverized marichino cherries, or Smuckers sunday topping such as Pine apple or other berry flavor. I make my own rub using a recipe from Paul Kirk's bbq bok and it is close to "Snails Sprinkle."
My method for comp cooks is pretty standard:
Smoke the ribs with apple and hickory mix until I like the color, about 2 to 3 hours
Place them meat down with a little apple juice in a foil pan and cover for about 1.25 hours
remove them and slop on the sauce and place them back in to stiffen them up and set the glaze, about 45 minutes.
I hold 250 as my temp of choice.
