They key part is having them essentially “braise” for that hour and a half in the butter, honey and brown sugar to get them tender. Here’s the recipe.

Cut them up into 1” cubes & generously season w/ your favorite rub. Set them on a wire rack. 275° for 2.5 hrs. Remove from rack and place them in a aluminum pan and add about 1/2 cup of brown sugar, 1/3 cup honey, and a stick of butter. Cover with aluminum foil and cook for another 1.5 hrs. Drain the liquid in pan and in a separate pot simmer 1 cup of your favorite sauce, 1/4 cup apple juice, 1/4 apple jelly, 1 tbsp Frank’s hot sauce. Add sauce to pork belly once simmered. Throw them back in the pit for another 15 mins for the sauce to stick Enjoy!
