Not to be an *ss because it looks yummy, but in all the meat/bbq threads I see lots of pics where the outside looks really burnt. Does it not spoil the taste? Or do you remove it a bit?
As others have noted, that blackened exterior is actually the goal. There was about a tablespoon of brown sugar in the dry rub, and it turns into this incredible sweet/smokey/savory “candy”.
Remember this is all done over indirect heat so you’re probably not going to get something “burned” in the conventional sense, although you can certainly dry something out into a hard little brick.
Toss in dried beans and water to flavor. Once done, you can remove the hocks and shred the meat to add back into the beans. The collagen really make the broth rich and the smoke gives a nice extra dimension.
