3-4 lb belly cut into 1" cubes, covered in rub of choice, on the BGE/smoker/pit for 2 hours for smoke at anywhere between 225 and 250.
Into a foil pan with a half stick of butter, a good handful of light brown sugar, a good drizzle of honey all over and a 1/4 cup of apple juice. That gets foiled and returned to the pit for at least 2 if not 2.5 hours. This is a braise and IMHO is key.
Remove from pan and glaze with mix of apple jelly, BBQ sauce, S&P. The jelly is neutral and sets the glaze. Back on the pit in a clean pan or rack for 20 minutes of so.
Eat until your belly is full. Do not share them. No one else in the house deserves a morsel of this gift from the BBQ gods.
Seriously, eat while hot. If they get cold they can get tough and chewy.
