So I used akjeff's method for making pork belly burnt ends with just a slight modification. I bought a 5+ lb pork belly from Costco and brined it for 24 hours in a mixture of 1 cup salt, 1 cup sugar, 1 TBS black peppercorns, and 2 bay leaves in 1 gallon of water. Brought to boil then simmered for 5 minutes. Cooled a little then added some ice. Put in pork belly then into fridge.
Next day, I rinsed and dried the pork belly. Cut into roughly 1 inch cubes. Coated in a mixture of a homemade rub, BPS Sweet Money, and Killer Hogs The BBQ Rub. Put on a mat on the top shelf of my MAK and smoked them for 2 hours.
After 2 hours, raised temp to 275F. Put cubes in an aluminum pan with butter, brown sugar, and honey. Covered. Back on the top shelf for another 2 hours.
After another 2 hours, lowered temp to 225F. Brought in aluminum pan and drained liquid. Coated cubes in BBQ sauce and put back on the mat on the top shelf for 1 hour. (I would have done 2 hours but it was getting late and I had some other stuff to do.)
The burnt ends turned out amazing. Very flavorful and melt in your mouth tender. I gave a sample of them to a coworker who said they were awesome. He offered to pay me for more of them (I gave him more free of charge. The complement was payment enough). I will definitely be making these again.
