Make ahead tip: Cook the ribs up to step 5, then refrigerate the wrapped ribs. On the day you want to eat them, remove from the fridge and let sit at room temperature for about 1 1/2 to 2 hours. Then proceed with step 6. This also works well if you're only cooking for 1 or 2 and can't finish a whole rack in one sitting. You can freeze some for another day - just let them thaw in the fridge overnight, then bring to room temperature before finishing them with sauce!
