Take the ribs out of the packaging and pat dry with a paper towel.
Place ribs on a cooking sheet.
Mix the sea salt, black pepper, chitpotle pepper, brown sugar, smoked paprika, garlic powder, Lowery’s salt, and brown sugar in a bowl and mix well.
Rub the mixed spices on both sides and then make sure the bone side is face down when you cook the ribs.
Cut the sweet potatoes in cubes and place in a bowl.
Mix the olive oils, freshly chopped rosemary and salt and pepper.
Place the potatoes on the cooking sheet with the ribs and place in oven. The ribs should take approximately 4 hours. The last hour baste some BBQ sauce on the ribs. Note that the potatoes may be done sooner than the ribs, so make sure you are checking in on the ribs and potatoes every hour.
