In a large bowl, add your pork neckbones. Rinse them in cold water. Rub and massage them to wash away blood or any bone dust.
Pour the water off and fill the bowl with fresh water. Add white distilled vinegar. Set aside to soak for at least 20mins. (This will allow any remaining blood to be pulled out)
Preheat oven to 350°F.
While the neckbones soak, make the seasoning.
To a small bowl, add the chipotle chili powder, onion powder, garlic powder, black pepper, Lawry's seasoning salt, knorr chicken bouillon, paprika, light brown sugar, and ground sage. Mix until well combined. Set aside.
Once neckbones are done soaking, pour water off.
Pat neckbones dry with a paper towel and arrange neckbone in a large baking dish.
Pour melted bacon grease all over neckbones, then sprinkle neckbones evenly with the prepared seasoning.
Use your hands to rub the grease and seasoning all over neckbones until they are evenly coated. Cover with aluminum foil and slide them into the preheated oven.
Bake covered for about 40 mins or until meat it fork tender.
Once neckbones are tender, uncover and brush with barbecue sauce. Back uncovered for another 15-20 mins, or until sauce is sticky
Remove from oven and Enjoy!!
