Preheat oven to 225 degrees. Take ribs out of the fridge 30 minutes before cooking them to come to room temperature.
Make the Chipotle BBQ sauce. In a blender, puree the 1 chipotle with the adobo sauce. Transfer to a small sauce pan and turn heat up to medium. Add remaining ingredients: brown sugar, honey, apple cider vinegar, garlic powder, broth, salt and pepper. Bring to a simmer and taste. If too spicy, add more honey. If too sweet, add a dash more adobo sauce until it fits your taste. Let simmer for 15 minutes, until slightly thickened. Remove from heat.
Coat the ribs in salt and pepper and then slather with BBQ sauce. Place a wire rack over a baking sheet. Add about 1/2 inch of water to the bottom of the baking sheet. Place the ribs on top of the wire rack and cover with foil. Pop into the oven for 4 hours (at 225 degrees). After 4 hours, remove the foil and let cook until the ribs are falling apart, basting with BBQ sauce every 15 minutes for another hour. Right before you remove them, turn on the broiler for 3-4 minutes to give some extra crunch. Alternatively, throw on the grill/grillpan for 5-7 minutes.
Remove and let cool for 10 minutes covered in foil. Cut ribs into 2s or 3s and serve with extra BBQ sauce.
